syscon: Move syscon code in dev/syscon
We've removed kernel option EXT_RESOURCES almost two years ago.
While it was ok to have some code under a common 'extres' subdirectory
at first, we now have a lot of consumer of it and we made it mandatory
so no need to have it under a cryptic name.

Refine locking inside of syscon driver.
In some cases, the syscon driver may be used by consumer requiring better
control about locking (ie. it may be used as registe file provider for clock
driver which needs locked access to multiple registers).
Add fine locking protocol methods together with bunch of helper functions
in syscon driver and implement this functionality in syscon_generic driver.
MFC after: 4 weeks

- declare coresponding method in syscon interface
- implement it in simple multifunction device driver

Move syscon into extres framework
This should help reduce confusion between syscon/syscons a little bit.
syscon is a resource generally modeled by FDT platforms, and not to be
confused with syscons.

syscon: Introduce kobj and split out fdt bits
Allow more flexibility by kobj'ifying syscon and splitting out fdt specific
bits in preparation of a move to the extres framework.
The generic fdt driver has been moved to syscon_generic.c and the fdt
requirement has been removed from the syscon interface, as is common to the
extres framework.

Add generic 'syscon' driver
Upstream dts for allwinner will require a syscon driver, since the emac node
coming in 4.15 will be using xref to /soc/syscon for configuring the emac
clock. Add a generic syscon driver to attach to /soc/syscon for use by
if_awg, providing basic read/write functionality to consumers.
syscon driver will also be used by arm64 at least for A64+H5 emac/if_awg.
