drivers: syscon: Add generic syscon API

Browse source 
A syscon device is a device managing a memory region containing a set of
registers that are not cohesive enough to represent as any specific type
of device. We need a driver for that because several other drivers could
use the same region at the same time and we need to io-map the region at
boot for MMU enabled platforms.
