Drop redundant header imports with dts/upstream already providing
updated headers which have been checked to be backwards compatibility.

The imx headers which aren't present in dts/upstream are as follows:

- include/dt-bindings/clock/imxrt1020-clock.h
- include/dt-bindings/clock/imx8qm-clock.h
- include/dt-bindings/clock/imxrt1170-clock.h
- include/dt-bindings/clock/imx8qxp-clock.h
- include/dt-bindings/memory/imxrt-sdram.h
- include/dt-bindings/pinctrl/pads-imx8qxp.h
- include/dt-bindings/pinctrl/pads-imx8qm.h
- include/dt-bindings/soc/imx8_pd.h
- include/dt-bindings/soc/imx_rsrc.h

hence these aren't dropped yet but there was an unused header:

- include/dt-bindings/pinctrl/pins-imx8mq.h

which has been dropped as well. There shouldn't be any funtional impact
with this change but it rather allows iMX platforms to use upstream
dt-bindings headers in a backwards compatible manner.

There are some newer clocks added to the kernel recently,
so to fix prepare for resycing the device trees, update
the clock list.  Since there are some minor changes to
the USB clocks, update which USB clocks are enabled
to match with the upstream kernel as well.
