[PATCH 1/2] arm64: dts: imx8qm-mek: correct the light sensor interrupt type to low level

[Haibo Chen]

light sensor isl29023 share the interrupt with lsm303arg, but these
two devices use different interrupt type. According to the datasheet
of these two devides, both support low level trigger type, so correct
the interrupt type here to avoid the following error log:

  irq: type mismatch, failed to map hwirq-11 for gpio@5d0c0000!

[PATCH 2/2] arm64: dts: add off-on-delay-us for usdhc2 regulator

[Haibo Chen]

For SD card, according to the spec requirement, for sd card power reset
operation, it need sd card supply voltage to be lower than 0.5v and keep
over 1ms, otherwise, next time power back the sd card supply voltage to
3.3v, sd card can't support SD3.0 mode again.

To match such requirement on imx8qm-mek board, add 4.8ms delay between
sd power off and power on.
