ARM: ks8695: add board support for the SnapGear boards based on the KS8695
A number of boards produced by SnapGear are based on the Micrel KS8695 SoC.
Add board support to the KS8695 kernel code to support them.
The following machine type entries will need to be added back into the
mach-types file with these in mainline:
lite300 MACH_LITE300 LITE300 408
se4200 MACH_SE4200 SE4200 809
sg310 MACH_SG310 SG310 1564
