[U-Boot] [PATCH v3 31/66] rockchip: rk3368: syscon: SGRF support for OF_PLATDATA

In TPL we will need to configure security in the SGRF of the RK3368.
This change adds support for the SGRF as a syscon device, so we can
retrieve its address range through the syscon API in TPL (and can
avoid having to hard-code the address).

Changes in v3:
- adds SGRF syscon support with OF_PLATDATA (to allow access to the
SGRF address range from TPL)

Changes in v2: None
