ARM: dts: bcm6846: Add GPIO blocks

Browse Source 
The BCM6846 has the same simplistic GPIOs as some other
Broadcom SoCs: plain memory-mapped registers with up to
8 blocks of 32 GPIOs each totalling 256 GPIOs.

Users of the SoC can selectively enable the GPIO blocks
actually used with a certain design.
