clk: imx95-blk-ctl: Add clock for i.MX94 LVDS/Display CSR

i.MX94 BLK CTL LVDS CSR's LVDS_PHY_CLOCK_CONTRL register controls the clock
gating logic of LVDS units. Display CSR's DISPLAY_ENGINES_CLOCK_CONTROL
register controls the selection of the clock feeding the display engine.

Add clock gate support for the two CSRs.
