According to commit e045f044e84e ("arm64: dts: imx8mq: Move usdhc clocks
assignment to board DT") add the clocks assignment to imx8mq-librem5.dtsi
too.

In order for the touchscreen interrupt line to work, describe it properly.
Otherwise it can work if defaults are ok, but we cannot be sure.

GPIO_ACTIVE_x flags are not correct in the context of interrupt flags.
These are simple defines so they could be used in DTS but they will not
have the same meaning:
1. GPIO_ACTIVE_HIGH = 0 = IRQ_TYPE_NONE
2. GPIO_ACTIVE_LOW = 1 = IRQ_TYPE_EDGE_RISING
Correct the interrupt flags, assuming the author of the code wanted same
logical behavior behind the name "ACTIVE_xxx", this is:
ACTIVE_LOW => IRQ_TYPE_LEVEL_LOW

The ti,tps6598x binding requires interrupt-names property. The driver
does not really use it but the hardware could have more interrupt lines
connected. This fixes dtbs_check warning:

The 'interrupt-names' property is not described in dtschema, not used by
the driver and does not really make sense as its value is simple 'irq'.
Drop it to fix dtbs_check warnings like:
arch/arm64/boot/dts/freescale/imx8mq-librem5-devkit.dt.yaml:
pmic@4b: 'interrupt-names' does not match any of the regexes: 'pinctrl-[0-9]+'

Add a devicetree description for the Librem 5 phone. 4 hardware revisions
have been available. Some revisions include changes that need different
software to be run. So far, r3 ("Dogwood") is one such example, see:
"Aspen" r0 not supported (very few devices exist)
"Birch" r1 supported by r2
"Chestnut" r2 added by this patch
"Dogwood" r3 added by this patch
"Evergreen" r4 tba / most likely supported by r3
See https://puri.sm/products/librem-5/ for more information.
This boots to a working console with working WWAN modem, wifi usdhc,
IMU sensor device, proximity sensor, haptic motor, gpio keys, GNSS and LEDs.
