[PATCH 1/2] ARM: imx: imx8m: Align PLL 1.2 GHz option with Linux

[Marek Vasut]

Linux uses slightly different divider settings for the 1.2 GHz PLL
configuration, adjust the coefficients to match Linux.

[PATCH 2/2] ARM: imx: imx8m: Add PLL 1.4 GHz, 1.5 GHz, 1.6 GHz, 1.8 GHz options

[Marek Vasut]

Add PLL 1.4 GHz, 1.5 GHz, 1.6 GHz, 1.8 GHz options for iMX8M SoCs
in case they should be operated faster, e.g. to improve boot time.
