22e08d541f hv: calculate hv_e820_ram_size dynamically
The e820 module could get the RAM info on run time, but the RAM size
and MAX address was limited by CONFIG_PLATFORM_RAM_SIZE which was
predefined by config tool.

Current solution can't support single binary for different boards or
platforms and the CONFIG_PLATFORM_RAM_SIZE can't matching the RAM size
if user have not update config tools setting after the device changed.

So this patch remove the CONFIG_PLATFORM_RAM_SIZE and calculate ram
size on run time.

d965f6e6a1 hv: Enlarge E820_MAX_ENTRIES to 64
e820_alloc_memory() splits one E820 entry into two entries. With vEPT
enabled, e820_alloc_memory() is called one more. On some platforms, the
e820 entries might exceed 32.

Enlarge E820_MAX_ENTRIES to 64. Please note, it must be less than 128
due to constrain of zeropage. Linux kernel defines it as 128.

688a41c290 hv: mod: do not use explicit arch name when including headers
Instead of "#include <x86/foo.h>", use "#include <asm/foo.h>".

In other words, we are adopting the same practice in Linux kernel.
