This is a preparation patch in order to add lxa-tac generation 3
board.
As the gen3 board has a different adc and gpio{e,g} setups, move these
from the stm32mp15xc-lxa-tac.dtsi to the gen{1,2}.dts files.

Some of the userspace software and tests depend on the can/i2c/spi
devices having the same name on every boot. This may not always be the
case based on e.g. parallel probe order.
Assign static device numbers to all can/i2c/spi devices.

The RTC was enabled under the false assumption that the SoM already
contains a suitable 32.768 kHz crystal.
It does however not contain such a crystal and since none is fitted
externally to the SoM the RTC can not be used on the hardware.
Reflect that in the devicetree.

According to the OSD32MP1 Power System overview[1] pwr_regulators;
vdd-supply and vdd_3v3_usbfs-supply are hard-wired internally in
the SIP module to vdd and ldo4.

This results in an improvement of EMI performance by reducing the
125MHz emission and its harmonics caused by the RGMII clock line.

This results in a slight improvement in EMI performance due to the lines
no longer being driven by the somewhat noisy VDD_IO supply of the SoM.

All machines making use of &usbh_ehci and/or &usbh_ohci use
phys = <&usbphyc_port0>;
So move this setting into the .dtsi. Also add
phy-names = "usb";
which isn't used by all machines, but nice for consistency.

The Linux Automation Test Automation Controller (LXA TAC)[1] is an embedded
software development tool built around the Octavo Systems OSD32MP15x SiP.
The device contains an eMMC for storage, a DSA-capable on board ethernet
switch with two external ports, dual CAN busses, a power switch to turn
a device under test on or off and some other I/O.
As of now there are two STM32MP157 based hardware generations (Gen 1 and
Gen 2) that have most of their hardware config in common.
In the future there will also be a STM32MP153 based hardware generation.
