This driver assumes that lpuart clock is already enabled before
probing but using DM only lpuart won't be automatically enabled so
add clk_enable() when probing if CONFIG_CLK is defined.

While adding support for OF_PLATDATA, I've realized that when using
OF_PLATDATA I can only use clk_get_by_index_platdata() but often imx
peripheral drivers(as done in Linux) get clock by name("per" clock)
instead of other clock sources. So here the problem is that I can't know
for sure which id "per" clock source will have. I wouldn't use 0 as
default clock-id since it's not sure "per" will be the 0 index.
And this will occur for fsl_esdhc_imx.c driver too.
Do you have any suggestions?
Thanks in advance
Best regards
