ARM: SoC fixes for v5.11, part 2

Browse Source 
These are the current arm-soc bug fixes for linux-5.11. I already merged
 a larger set that just came in during the past three days but has not
 had much exposure in linux-next, so these are the ones I merged last week.
 
 Most of these are for the NXP i.MX platform (descriptions from their
 pull request):
 
  - Fix pcf2127 reset for imx7d-flex-concentrator board.
  - Fix i.MX6 suspend with Thumb-2 kernel.
  - Fix ethernet-phy address issue on imx6qdl-sr-som board.
  - Fix GPIO3 `gpio-ranges` on i.MX8MP.
  - Select SOC_BUS for IMX_SCU driver to fix build issue.
  - Fix backlight pwm on imx6qdl-kontron-samx6i which is lost from
    #pwm-cells conversion.
  - Fix duplicated bus node name for i.MX8MN SoC.
  - Fix reset register offset on LS1028A SoC.
  - Rename MMC node aliases for imx6q-tbs2910 to keep the MMC device
    index consistent with previous kernel version.
  - Selecting ARM_GIC_V3 on non-CP15 processors to fix one build failure
    with i.MX8M SoC driver.
  - Fix typos with status property on imx6qdl-kontron-samx6i board.
  - Fix duplicated regulator-name on imx6qdl-gw52xx board.
 
 Aside from i.MX, the bugfixes are all over the place:
 
  - Coccinelle found a refcount imbalance on integrator
  - defconfig fix for TI K3
  - A boot regression fix for ST ux500
  - A code preemption fix for the optee driver
  - USB DMA regression on Broadcom Stingray
  - A bogus boot time warning fix for at91 code
