Use of MMR3PhysGetRamSizeU

[Winbagility]

Hello,

We should use MMR3PhysGetRamSizeU()

for:

icebox/third_party/virtualbox/src/VBox/VMM/VMMAll/PGMAll.cpp

Line 1504 in eafbeb6

if(GCPhys < MEMORY_SIZE)

and:

icebox/third_party/virtualbox/include/VBox/vmm/vm.h

Line 103 in eafbeb6

#define MEMORY_SIZE 0x200000000

Thank you.
