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.
