drm/msm/dsi: Add byte_intf_clk

Browse source

DSI6G v2.0+ blocks have a new clock input to them called
byte_intf_clk. It's rate is to be set as byte_clk / 2.

Within the clock controller (CC) subsystem, this clock is a
child/descendant of the byte_clk.

Set it up as an optional clock in the DSI host driver. Make sure
that we enable/set its rate only after we configure byte_clk.
This is required for the ancestor clocks in the CC to be
configured correctly.
