7279b82cb1 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.

Needed for LEON AMP systems where different CPUs are routed to

different IRQ controllers. This patch selects the IRQ Controller
which has been routed to the boot CPU, it is up to the boot loader
to configure the IRQ controller.

5213a78029 sparc,leon: CONFIG_SPARC_LEON option and leon specific files. 
The macro CONFIG_SPARC_LEON will shield, if undefined, the sun-sparc
code from LEON specific code. In
particular include/asm/leon.h will get empty through #ifdef and
leon_kernel.c and leon_mm.c will not be compiled.
