[PATCH 1/2] arm:omap:am33xx: SoC type detection

[Afzal Mohammed]

Determine SoC type, i.e. whether GP or not

Note: cpu_is_34xx() is true for am33xx also. Doing
cpu_is_am33xx() check after cpu_is_34xx() will not
achieve what we want due to the above reason.
Hence cpu_is_am33xx() is done before cpu_is_34xx()
