If HV relocation is enabled, either ACRN efi-stub or GRUB relocates
hypervisor image above HPA 256MB, thus we put hvlog and ramoops buffer
under 256MB to avoid conflict with hypervisor owned address.
This patch hardcodes these addresses:
0xa00000 - 0xdfffff: 4MiB for ramoops buffer
0xe00000 - 0xffffff: 2MiB for hvlog buffer
However, user can customize them to other addresses as long as it's under
256MB, available in host e820, and SOS bootarg "nokaslr" is not specified.
If HV relocation is disabled, need to make sure that these buffer
addresses are not between HV_RAM_START and HV_RAM_START + HV_RAM_SIZE.

- remove limit of CONFIG_HV_RAM_SIZE which is for scenario of 2 VMs only,
the default size from Kconfig could build scenario which up to 5 VMs;
- rename whl-ipc-i5_acpi_info.h to platform_acpi_info.h, since the former
one should be generated by acrn-config tool;
- add SOS related macros in misc.h, otherwise build scenarios which has
SOS VM would be failed;
