Add the below flags, they are needed in -O2:
-fno-delete-null-pointer-checks:
* tells the compiler NOT to assume that null pointer deference does
not exist.
* Without this flag, below case cannot be detected:
a pointer might point to nullsometime during run-time and if there
is no validation for that pointer, it will cause the program to crash.
Since we don’t receive an error message saying that a pointer is
pointing to null, we will have a hard time trying to find the problem.
-fwrapv:
* tells the compiler that signed overflow always wraps.
* Without this flag, x + 10 > x will always be true for signed x.
With the flag, x + 10 > x is not always be true, as the overflow is
defined for x, and it could wrap.

Add a Kconfig parameter called UEFI_OS_LOADER_NAME to hold the Service VM EFI
bootloader to be run by the ACRN hypervisor. A new string manipulation function
to convert from (char *) to (CHAR16 *) has been added to facilitate the
implementation.
The default value is set to systemd-boot (bootloaderx64.efi)

Now ACRN support more and more platforms. However, the default configuration only
support board which memory is less than 16 GB. If a board memory is large than
16 GB, the developer needs to configure the memory configuration according to his
board. Otherwise, the boot will fail. This's because UEFI BIOS will use the high
memory as possible.
This patch try to allocate the memory as eraly as possible. So that the BIOS will
not access this region.

To be back compatible, the default acrn.efi should be built when
BOARD param is nuc6cayh, because apl-nuc was overridden to nuc6cayh
in acrn-hypervisor/Makefile;

1. if SCENARIO=$(SCENARIO) is specified in make param, then override
the default CONFIG_$(SCENARIO) value in existed .config. This means
we don't need to modify the default SCENARIO config in Kconfig file
to build the hypervisor;
2. Some board name shortcuts like apl-nuc/kbl-nuc-i7 need to be converted
to official board name to make sure overrides working;
3. Previously make sbl-hypervisor did not load the defconfig so the
defconfig for boards are lost, this patch fix this issue;
4. remove SCENARIO param when make hypervisor, because SCENARIO could
be got from SCENARIO_NAME which parsed from .config;

We are trying to add both industry and sdc images to CL build. To
maintain the build interface unchanged (no change from CL side), we
extend the build command to generate the different target images.
To identity different images, we use rule:
$(HV_FILE).$(BOARD).$(FIRMWARE).$(SCENARIO)
as target image file name.
