Pull ARM SoC DT fixes from Arnd Bergmann:
 "These are the latest device tree fixes for Arm SoCs:

   - TI Keystone2 ethernet regressed after a driver change broke with
     incorrect phy-mode in a board's DT source.

   - A similar fix is needed for two i.MX boards that were missed in an
     earlier bugfix.

   - DT change for Armada 38x allowing to add the register needed to fix
     NETA lockup when repeatedly switching speed.

   - One fix on imx6qdl-icore pin muxing to get USB OTG_ID and SD card
     detect work correctly.

   - Two fixes for the Allwinner SoCs, one to relax the CMA allocation
     ranges that were failing on older SoCs and one to fix Cedrus on the
     H6"

Since commit bcf3440c6dd7 ("net: phy: micrel: add phy-mode support for the
KSZ9031 PHY") the networking is broken on keystone-k2g-evm board.

The above board have phy-mode = "rgmii-id" and it is worked before because
KSZ9031 PHY started with default RGMII internal delays configuration (TX
off, RX on 1.2 ns) and MAC provided TX delay by default.
After above commit, the KSZ9031 PHY starts handling phy mode properly and
enables both RX and TX delays, as result networking is become broken.

Fix it by switching to phy-mode = "rgmii-rxid" to reflect previous
behavior.

Commit

  84e6ffb2c49c7901 ("arm: add support for folded p4d page tables")

updated create_mapping_late() to take folded P4Ds into account when
creating mappings, but inverted the p4d_alloc() failure test, resulting
in no mapping to be created at all.

When the EFI rtc driver subsequently tries to invoke the EFI GetTime()
service, the memory regions covering the EFI data structures are missing
from the page tables, resulting in a crash like

__vdso_*() should be removed and fallback used if CNTCVT is not
available by cntvct_functional(). __vdso_clock_gettime64 when added
previous commit is using the incorrect CNTCVT value in that state.
__vdso_clock_gettime64 is also added to remove it's symbol.
