Save the pointer of efi_ctx in mi_drivers_addr field of
multiboot structure and pass to hypervisor, not by
saving in register RDX(the third default parameter in
64bit call function).
With this method, we can be compatible with the original
32bit boot parameters passing method and no need to
large the array size of boot_regs in hypervisor.

With current code, the acrn.efi is inserted between
cl bootloader.efi and bzImage.efi that destroyed the chain
relationship of cl bootloader and cl bzImage.efi.
And the following is current boot flow:
UEFI -> cl bootloader.efi -> acrn.efi -> bzImage.efi
The purpose of this patch is resume above chain relationship,
and make uefi vm return to efi stub context once launched,
then continue to call the UEFI API(LoadImage/StartImage) to launch
cl bootloader or other bootloaders. So the boot flow will
change to be as below:
UEFI -> acrn.efi -> cl bootloader.efi -> bzImage.efi
After applying this patch, the code related to loading
bzImage.efi and getting pe_entry is unnecessary due to
the bzImage.efi will not be launched by acrn.efi directly,
so it is removed.

With current code, memcpy rsdp to 0x500 maybe overwrite uefi
code/data region.
So remove the legacy BIOS deliver method of RSDP, which need copy
the RSDP to EBDA space which is addressed by the 16bit pointer
at 0x40E or upper memory BIOS space 0xe0000-0xfffff. And just
deliver the pointer of RSDP, which is already saved in UEFI system
table, to hypervisor.
Create a function named efi_init() to separate efi initialize code.

UOS_Loader will trigger boot of Trusty-OS by HC_INITIALIZE_TRUSTY.
UOS_Loader will load trusty image and alloc runtime memory for
trusty. UOS_Loader will transfer these information include
trusty runtime memory base address, entry address and memory
size to hypervisor by trusty_boot_param structure.
In hypervisor, once HC_INITIALIZE_TRUSTY received, it will create
EPT for Secure World, save Normal World vCPU context, init
Secure World vCPU context and switch World state to Secure World.

For ARM, The SMC instruction is used to generate a synchronous
exception that is handled by Secure Monitor code running in EL3.
In the ARM architecture, synchronous control is transferred between
the normal Non-secure state and the Secure state through Secure
Monitor Call exceptions. SMC exceptions are generated by the SMC
instruction, and handled by the Secure Monitor.The operation of
the Secure Monitor is determined by the parameters that are passed
in through registers.
For ACRN, Hypervisor will simulate SMC by hypercall to switch vCPU
State between Normal World and Secure World.
There are 4 registers(RDI, RSI, RDX, RBX) reserved for paramters
passing between Normal World and Secure World.

There are two things here:
1. Enable basic vsbl boot functionality.
2. add long option to DM to specific vsbl file. So DM could
choice to boot guest with vsbl.
It's hard to find a suitable short option. So only long option
is supported for vsbl file name option.
If long option "--vsbl='vsbl_file_name'" is given in DM
commandline, the "vsbl_file_name" will be loaded by DM
first and running. vsbl will be response to lead guest to
next boot stage.

Some virtio PCI devices can change the device configuration state, as
reflected in the device-specific configuration region of the device. In
this case:
* If MSI-X capability is disabled:
1. Set the second lower bit of the ISR Status field for the device
2. Send the appropriate PCI interrupt for the device.
* If MSI-X capability is enabled:
1. If config_msix_vector is not NO_VECTOR, request the appropriate
MSI-X interrupt message for the device, config_msix_vector sets
the MSI-X Table entry number.
A single interrupt MAY indicate both that one or more virtqueue has been
used and that the configuration space has changed.

There are two TODOs of this patch:
1. This patch only update the uCode on pCPUs SOS owned. For the
pCPUs not owned by SOS, the uCode is not updated. To handle
this gap, we will have SOS own all pCPUs at boot time. So
all pCPUs could have uCode updated. This will be handled
in the patch to enable SOS own all pCPUs at boot time.

As mentioned in https://github.com/projectacrn/acrn-documentation/pull/38
on some operating systems, the ``gnu-efi`` package installs the
linker under a ``gnuefi`` folder in ``${LIBDIR}``. This is the
case in Fedora for example. Check if the gnuefi folder is there
and use it if it is in the path to the linker. This PR fixes the
Makefile rather than documenting how to edit it yourself.
