mm: check phys_to_xxxx macro on 32bit OS [1/1]

PD#SWPL-1909

Problem:
If physical address of a memory location is not in linear mapping
range, then any caller with phys_to_xxxx to get a pointer will
cause bug.

Solution:
Check input address range for phys_to_xxxx to get a BUG output.
This change is used for debug

Verify:
P212
