Removal of more old SoC support

[Andrew Turner]

I'm planning on removing some old ARMv4/ARMv5 SoC support from HEAD. The
following directories will be removed:
 samsung/s3c2xx0
 xscale/i80321
 xscale/i8134x

These config files will be removed as they build the code in one of the
above directories: CRB, EP80219, IQ31244, LN2410SBC. Any further config
files are expected to stay. This won't touch the AVILA, or CAMBRIA
files.

Does anyone have any objections to this?
