Similar to i.MX95, i.MX94 also has LVDS/DISPLAY CSR to provide
clock gate for LVDS and DISPLAY Controller. So following same approach
to add the support, as what have been done for i.MX95.

Patch 1 is to add the binding doc.
Patch 2 is fixes when supporting i.MX94, but the issues are
also exposed to i.MX95 even not triggered. No need to rush the
two patches for 6.16.
Patch 3 and 4 is to add the clk driver. Patch 3 is almost picked from
NXP downstream with a minor update. Patch 4 is modified from NXP
downstream with a few minor patches merged and updated.
Patch 5 is the dts part to give reviewer a whole view on how it is used.

Thanks for Frank Li helping do NXP internal review for the patchset.
