arm64: dts: meson-g12: split emmc pins to select 4 or 8 bus width

The Khadas VIM3 shares the eMMC pins 4 to 7 with the SPI NOR, in order
to enable the eMMC and the SPI NOR interface, we need to omit the
4 last pins from the eMMC pinctrl.

As it was done for the Khadas VIM2, split the eMMC pinctrls in ctrl, data
and ds pins with either 4bits data or 8bits data, and update the current
board accordingly.

arm64: dts: meson-sm1-sei610: enable DVFS

This enables DVFS for the Amlogic SM1 based SEI610 board by:
- Adding the SM1 SoC OPPs taken from the vendor tree
- Selecting the SM1 Clock

arm64: dts: meson-sm1-sei610: enable DVFS

This enables DVFS for the Amlogic SM1 based SEI610 board by:
- Adding the SM1 SoC OPPs taken from the vendor tree
- Selecting the SM1 Clock controller instead of the G12A one
- Adding the CPU rail regulator, PWM and OPPs for each CPU nodes.

Each power supply can achieve 0.69V to 1.05V using a single PWM
output clocked at 666KHz with an inverse duty-cycle.

DVFS has been tested by running the arm64 cpuburn at [1] and cycling
between all the possible cpufreq translations of the cpu cluster and
checking the final frequency using the clock-measurer, script at [2].

Add support for the Amlogic SM1 Based SEI610 board.

The SM1 SoC is a derivative of the G12A SoC Family with :
- Cortex-A55 core instead of A53
- more power domains, including USB & PCIe
- a neural network co-processor (NNA)
- a CSI input and image processor
- some changes in the audio complex, thus not yet enabled

The SEI610 board is a derivative of the SEI510 board with :
- removed ADC based touch button, replaced with 3x GPIO buttons
- physical switch disabling on-board MICs
- USB-C port for USB 2.0 OTG
- On-board FTDI USB2SERIAL port for Linux console

Audio, Display and USB support will be added later when support of the
corresponding power domains will be added, for now they are kept disabled.
