Drop from 5.15 and older -- clk: imx: pll14xx: dynamically configure PLL for 393216000/361267200Hz

[Marek Vasut <marex@xxxxxxx>]

Please drop the following commits from stable 5.10.y and 5.15.y respectively

972acd701b19 ("clk: imx: pll14xx: dynamically configure PLL for 
393216000/361267200Hz")
a8474506c912 ("clk: imx: pll14xx: dynamically configure PLL for 
393216000/361267200Hz")

The commit message states 'Cc: stable@xxxxxxxxxxxxxxx # v5.18+'
and the commit should only be applied to Linux 5.18.y and newer,
on anything older it breaks PLL configuration due to missing
prerequisite patches.

Thanks
