This board, as well as some other boards with i.MX6 and a PMIC, uses a
"PMIC_STBY_REQ" line to notify the PMIC about a state change.
The PMIC is programmed for a specific state change before triggering the
line.
In this case, PMIC_STBY_REQ can be used for stand by, sleep
and power off modes.

The pinctrl properties on the IOMUXC node get overwritten by the
carrier board level device tree, hence the pinctrl_reset_moci
pinctrl does not get applied.

Associate the pinctrl_reset_moci pinctrl with the PCIe node where
we also make use of the pin as a reset GPIO.

Since the pin is muxed as a GPIO by default not muxing it explicitly
worked fine in practise.

Signals available on both i.MX6UL and i.MX6ULL should have the same name
because it is the case of all others common signals, it avoids to make
mistakes (use the wrong ones) and it makes writing device tree files
less complicated. For example:

imx6ul-imx6ull-board.dtsi:
 ...
 pinctrl_uart5: uart5grp {
	fsl,pins = <
		MX6UL_PAD_UART5_TX_DATA__UART5_DCE_TX   0x1b0b1
	 	MX6UL_PAD_UART5_RX_DATA__UART5_DCE_RX   0x1b0b1
 	 >;
 };

imx6ul-board.dts:
 #include <imx6ul.dtsi>
 #include <imx6ul-imx6ull-board.dtsi>
 ...

imx6ull-board.dts:
 #include <imx6ull.dtsi>
 #include <imx6ul-imx6ull-board.dtsi>
 ...

Without this patch, the imx6ull-board.dtb will use
MX6UL_PAD_UART5_RX_DATA__UART5_DCE_RX instead of
MX6ULL_PAD_UART5_RX_DATA__UART5_DCE_RX and the uart5 will be

The "EDIMM STARTER KIT i.Core 1.5 MIPI Evaluation" is based on the 1.5 version
of the i.Core MX6 cpu module. The 1.5 version differs from the original one for
a few details, including the ethernet PHY interface clock provider.

With this commit, the ethernet interface works properly:
