ARM: AM437X: Add Silicon ID support
Add silicon ID code for AM437x silicon. This can be used to print the cpu info using CONFIG_DISPLAY_CPUINFO. Also printing "CPU :" along with cpu name in order to be consistent with other OMAP platforms. Reviewed-by: Tom Rini <trini@konsulko.com> Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com>
