Remove inaccurate compatible string 'mediatek,mt7986-ethsys' which
results in the wrong clock driver probing on MT7981 with Linux 6.1 and
ends up freezing the system once WED is used.

Add environment settings for the BananaPi BPI-R4 router board which
can boot from (and store its bootloader environment on) micro SD card,
SPI-NAND and eMMC.
Signed-off-by: Daniel Golle <daniel@makrotopia.org>
Hardware
--------
SOC: MediaTek MT7988A (4x Cortex-A73)
RAM: 4 GiB DDR4
Flash: 128 MiB Winbond SPI-NAND
MMC: 8 GiB eMMC *or* microSD (cannot be used both)
ETH: 4x 1GE (1x WAN, 3x LAN)
2x SFP+ (10G, 5G, 2.5G, 1G)
USB: on-board USB 3.2 4-port hub
1x USB 3.2 port (type A connector)
1x M.2 for 4G/5G modem
2x mPCIe for additional modems
WiFi: optional MediaTek MT7996 Wi-Fi 7 module
(using 2x PCIe gen3 x2 on the mPCIe slots and 12V power)
Installation
------------
1. Decompress and write the sdcard image to a micro SD card and use that
to boot the R4 (both dip switches in upper position).
2. Use the bootloader menu accessible via the serial console to install
to SPI-NAND.
3. Switch to boot from SPI-NAND and install to eMMC.
Known issues
------------
- The RST button is hard-wired to the SoC reset and can't be read
from software. This can be changed by modifying the board (ie.
moving a 0-ohm resistor). However, in order to maintain compatibility
with the board as it comes from factory the button isn't used by
OpenWrt and the WPS button is used as factory/reset button instead.
- various small things still need to be fixed in DT

Add UART pinctrl group for using only pins 80 and 81 for uart1.
This is needed on the BPi-R4 as RTS/CTS signals are used for other
on-board functions.

Replace previous patch adding paths and SerDes modes with patch series
pending upstream adding dedicated drivers for XFI T-PHY and USXGMII PCS,
extends LynxI PCS to be a standalone platform driver and as a consequence
makes much less changes to the actual Ethernet driver mtk_eth_soc.

Quite a few `fiilogic` devices use the `mt7531` switch.
Some of them have a DT node that looks like:
```
switch: switch@0 {
compatible = "mediatek,mt7531";
reg = <31>;
...
};
```
This commit changes the DT node name to `switch@1f`.

This doubles the number of cooling-levels.
In addition the fan is turned on with a low speed at lower temperatures
and with a higher speed at higher temperatures.
This also attempts to reduce the likelihood of constant start-stop actions.
The change only affects the GL.iNet MT3000 and has been tested with it.

Add build for the MTK3943 reference board for MT7981B+MT7976C.
**Hardware specification:**
- SoC: MediaTek MT7981B 2x A53
- Flash: various options
- RAM: 256MB DDR3
- Ethernet: 4 x 10/100/1000 Mbps via MT7531AE switch
EITHER 1 x 10/100/1000 Mbps built-in PHY
OR 1 x 10/100/1000/2500 Mbps MaxLinear GPY211C
- Switch: MediaTek MT7531AE
- WiFi: MediaTek MT7976C
- Button: RST, WPS
**Flash instructions for SPIM-NAND:**
- write *mt7981-rfb-spim-nand-preloader.bin to 'BL2' partition
- write *mt7981-rfb-spim-nand-bl31-uboot.fip to 'FIP' partition
- erase 'ubi' partition
- reset board
- create ubootenv and ubootenv2 UBI volumes in U-Boot
- edit environment and set bootcmd, e.g.
setenv bootconf 'config-1#mt7981-rfb-spim-nand#mt7981-rfb-mxl-2p5g-phy-eth1'
setenv bootcmd 'ubi read $loadaddr fit; bootm $loadaddr#$bootconf'
- load initramfs image via TFTP:
setenv serverip 192.168.1.254
setenv ipaddr 192.168.1.1
setenv bootfile openwrt-mediatek-filogic-mediatek_mt7981-rfb-initramfs.itb
saveenv ; saveenv
tftpboot
bootm $loadaddr#$bootconf
- Now use sysupgrade to write OpenWrt firmware to flash.
SNFI-NAND, SPIM-NOR and eMMC all work very similar, a bootable SD card image
is also being generated. However, as the board I've been provided only comes
with SPIM-NAND all other boot media are untested.

Fix the issue of dts buswidth cannot be applied properly with spi driver.
Fix the name of buswidth to bus-width in dts in order to fit the format
in linux spi kernel[1] so that spi-tx-bus-width & spi-rx-bus-width can be
parsed properly.

The PHY driver needs to read a register containing the values of the
bootstrap pins (which happen to be the PHY LEDs) to determine the LED
polarities. Allow regmap access to first pinctrl bank by adding the
'syscon' compatible, and reference the pinctrl in the MDIO bus where
the PHY driver will look for it.
