From: Paul Boddie <paul@boddie.org.uk>
Add support for the Lumissil/Ingenic X1600 SoC.
It uses shadow registers to commit changes to multiple pinctrl
registers in parallel.
Define specific Chip ID, register offsets, pin tables etc.
Handling the unique X1600_GPIO_PU only for the x1600 but
not for x1830 and above must be carefully taken into account.
