[PATCH 2/4] dt-bindings: mfd: syscon: Add ti,am625-dss-clk-ctrl

[Louis Chauvet <louis.chauvet@bootlin.com>]

The dt-bindings for the multi-function device (mfd) syscon need to include
ti,am625-dss-clk-ctrl. On AM625 chips, the display controller (tidss) has
external registers to control certain clock properties. These registers
are located in the device configuration registers, so they need to be
declared using syscon. They will later be used with a phandle in the tidss
node.

Fixes: 32a1795f57ee ("drm/tidss: New driver for TI Keystone platform Display SubSystem")
