[i.MX8MP/i.MX93][DRIVER] Fix display clk tree configuration

This fixes b33b6536, which broke the
build for mx93evk.

The error was related with undefine enum values introduced be this
commit which where declared in the imx8m/clock.h which is used in
the lcdif driver. It is used in the lcdif driver and also outside
to configure the related clocks. As the 'mxs_set_lcdclk is also
abstracted and does different things depending on the build config,
I think a better aproach is to keep the lcdif_type only inside the
lcdif driver and add another function to configure the 2nd lcd interfaces
clocks, called 'mxs_set_lcdclk_2nd'.
