reset: imx7: Add plubming to support multiple IP variants ...

Port of a Linux commit cffaab8

  In order to enable supporting i.MX8MQ with this driver, convert it to
  expect variant specific bits to be passed via driver data.

Port of a Linux commit 685efff

  The GPCv2 on the Freescale i.MX8MQ SoC works in the same way as the
  GPCv2 on the i.MX7, but only controls more power domains with a
  different mapping.

Port of a Linux commit 73f5971

  i.MX8MQ and i.MX8MM share same gpc module with i.MX7D, they
  can reuse gpcv2 pgc driver for power domain control, this
  patch renames all functions and structure definitions started
  with "imx7" to "imx", and use .data in imx_gpcv2_dt_ids[] to
  pass platform specific power domain data for power domain
  driver, thus make gpcv2 pgc driver more generic for i.MX
  platforms.

PCI: dwc: Fix pointer width cast problem ...

Casting to u32 works well on 32-bit builds, but causes problem when
compiled on 64-bit machines. Switch it to cast to "unsigned long", so
that it would have appropriate width in both cases.

While at it, replace explicit casts to void * with IOMEM.

net: fec_imx: skip fec_halt if the FEC wasn't started ...

If the FEC driver is enabled, but the ethernet device was never
opened due to booting from another source the wait for graceful
transmit stop will always fail. This introduces an unnecessary
boot delay and prints a distracting warning.

As there is no point in trying to shut down the FEC if it was
never started, just skip all of fec_halt in that case.
