Igor Mammedov 8dfba500af memhp: consolidate scattered MHPD device declaration 
since static and dynamic parts of memory MHPD device are now
in the same table (DSDT), there is no point keeping
them scattered across the table, so consolidate it
in one place.

There aren't any functional change, only AML text movement
from externally refferenced MHPD scope directly into
MHPD device declaration.
