Per SDM Vol. 2:
If CPUID.80000008H:EAX[7:0] is supported, the maximum physical address
number supported should come from this field.
This patch gets the maximum physical address number from CPUID leaf
0x80000008 and calculates the physical address mask when the leaf is
available.
Currently ACRN does not support platforms w/o this leaf and will panic
on such platforms.
Also call get_cpu_capabilities() earlier since the physical address mask
is required for initializing paging.
