[PATCH v2 0/9] Add imx8ulp clock & reset driver support

[Jacky Bai <ping.bai@nxp.com>]

This patchset adds the clock & reset driver support for i.MX8ULP.
For some of the PCC slot, As there is a SWRST control bit share
the same pcc register for peripheral reset ccontrol. To simplify
the case, register the pcc reset controller driver when pcc
clock driver is registered.

Patch 1/9  for the dt-bindings part is send out for review previously
with the dts patchset:
https://patchwork.kernel.org/project/linux-arm-kernel/cover/20210607083921.2668568-1-ping.bai@nxp.com/

Shawn suggests to send out the clock driver part firstly, so this
patch is included in this patchset for now.

v2 changes:
  - remove the useless clocks & clock-names from the dt-binding doc
  - remove the redundant fixed clock register.
