Add max_tmds_clock validation to prepare for additions and changes to
the MPLL config table. Use the same rate restrictions that is currently
applied.

The rate limit for RK3288, RK3399 and RK3568 is based on current mpll
table. The rate limit for RK3228 and RK3328 is based on the
inno-hdmi-phy pre-pll table.
