[PATCHv2 1/4] ARM: Introduce SoC Info into /proc/cpuinfo

[Eduardo Valentin]

From: Eduardo Valentin <eduardo.valentin at nokia.com>

This patch extends the ARM /proc/cpuinfo to include soc info data.
It is implemented via the same way which is done for
system_rev, system_serial_low and system_serial_high.
Then, now we have system_soc_info, which is printed only
if there is something useful there.
