This commit adds the support for this IP.

Required properties:
|
|
- compatible: must be "technologic,ts4800-ts"
|
|
- reg: physical base address of the controller and length of memory mapped
|
|
region.
|
|
- syscon: phandle / integers array that points to the syscon node which
|
|
describes the FPGA's syscon registers.
