SPARC/LEON: power down instruction different of different LEONs
The way a LEON is powered down is implemented differently depending
on CHIP type. The AMBA Plug&Play system ID tells revision of GRLIB
and CHIP.
This is for example needed by the GR-LEON4-ITX board and the UT699.
Previously the power down support for LEON was limited to SMP, now
both SMP and UP systems use the instruction.
