This clock is critical for the system since it supplies the 32k SoC
clock. Unfortunately the imx8mm.dtsi uses a fixed clock provider for the
32k SoC clock and not this one. If it would use this clock we would add
a cycle-dependency since the pmic driver depends on the i2c driver which
depends on the clock driver. Therefore use the new "clocks-always-on"
macro to mark the clock as critical, so it is never turned off by the
kernel.
