There is build warning when CONFIG_OF is not selected.

Use CONFIG_OF to guard imx93_clk_of_match to avoid build warning.

Hmm, I'm not sure if we should do this or rather should we make this driver
depend somehow on CONFIG_OF in Kconfig.

Looking at the other i.MX clock drivers, it would seem we need this for
all them too.

I fairly OK with this, but maybe Stephen suggests something different.

No. It is i.MX93 use of_match_ptr, I could drop it as i.MX8M.

Thanks,
Peng.
