Subject: [PATCH v5 4/4] clk: imx: add i.MX91 clk
Reuse i.MX93 clk driver for i.MX91, because i.MX91 reuses the
Clock Control Module from i.MX93, with only a few clocks removed
and a few clocks added.
For clocks specific to i.MX93 use PLAT_IMX93 to flag them, for
clocks specific to i.MX91, use PLAT_IMX91 to flag them. Others
are shared by both.
