Generic GPIOs pinctrl nodes are not correct, gpio[1-4] are into the MCU
domain and should be into &mcu_gpio0, gpio[5-8] were missing and are added
in this commit.

Add a GPIO hog to release PCIe reset on the carrier board, this is
required to use M.2 or mPCIe cards.
Verdin AM62 does not have any PCIe interface, however the Verdin family
has PCIe and normally an M.2 or mPCIe slot is available in the carrier
board that can be used with cards that use only the USB interface toward
the host CPU, for example cellular network modem.

I have applied the following to branch ti-k3-dts-next on [1].
Thank you!
[1/2] arm64: dts: ti: verdin-am62: mallow: fix GPIOs pinctrl

[2/2] arm64: dts: ti: k3-am625-verdin: add PCIe reset gpio hog
commit: d3c702186abe01e24f962627ec67fcad8106c79d
All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent up the chain during
the next merge window (or sooner if it is a relevant bug fix), however if
problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying
to this mail.
