SOS_RAM_SIZE/UOS_RAM_SIZE Kconfig are only used to calculate how many pages we
should reserve for the VM EPT mapping.
Now we reserve pages for each VM EPT pagetable mapping by the PLATFORM_RAM_SIZE
not the VM RAM SIZE. This could simplify the reserve logic for us: not need to
take care variable corner cases. We could make assume we reserve enough pages
base on the VM could not use the resources beyond the platform hardware resources.
So remove these two unused VM ram size kconfig.

For FuSa's case, we remove all dynamic memory allocation use in ACRN HV. Instead,
we use static memory allocation or embedded data structure. For pagetable page,
we prefer to use an index (hva for MMU, gpa for EPT) to get a page from a special
page pool. The special page pool should be big enougn for each possible index.
This is not a big problem when we don't support 64 bits MMIO. Without 64 bits MMIO
support, we could use the index to search addrss not larger than DRAM_SIZE + 4G.
However, if ACRN plan to support 64 bits MMIO in SOS, we could not use the static
memory alocation any more. This is because there's a very huge hole between the
top DRAM address and the bottom 64 bits MMIO address. We could not reserve such
many pages for pagetable mapping as the CPU physical address bits may very large.
This patch will use dynamic page allocation for pagetable mapping. We also need
reserve a big enough page pool at first. For HV MMU, we don't use 4K granularity
page table mapping, we need reserve PML4, PDPT and PD pages according the maximum
physical address space (PPT va and pa are identical mapping); For each VM EPT,
we reserve PML4, PDPT and PD pages according to the maximum physical address space
too, (the EPT address sapce can't beyond the physical address space), and we reserve
PT pages by real use cases of DRAM, low MMIO and high MMIO.

Current memory allocation algorithm is to find the available address from
the highest possible address below max_address. If the function returns 0,
means all memory is used up and we have to put the resource at address 0,
this is dangerous for a running hypervisor.
Also returns 0 would make code logic very complicated, since memcpy_s()
doesn't support address 0 copy.

This patch denies Service VM the access permission to device
resources owned by pre-launched VMs.
Rationale:
* Pre-launched VMs in ACRN are independent of service VM,
and should be immune to attacks from service VM. However,
current implementation exposes the bar resource of passthru
devices to service VM for some reason. This makes it possible
for service VM to crash or attack pre-launched VMs.
* It is same for hypervisor owned devices.
NOTE:
* The MMIO spaces pre-allocated to VFs are still presented to
Service VM. The SR-IOV capable devices assigned to pre-launched
VMs doesn't have the SR-IOV capability. So the MMIO address spaces
pre-allocated by BIOS for VFs are not decoded by hardware and
couldn't be enabled by guest. SOS may live with seeing the address
space or not. We will revisit later.
