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.

Unfortunately some device tree properties have slipped under the table

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.

Add dependency to '32k' ADC clock so it is always enabled for thermal
and raw access to ADC values. This allows to remove the patch for the
ADC driver and reduce the patch adding thermal support for MT7986 to
only add the new efuse layout and temperature decoding for V3.

* set correct clocks for PWM to work.
* MT7986 PWM does have the 26MHz-clock-select, set that in patch
* drop useless 'passive' trip point in thermal zone
* extend pwm-fan to have 3 active operating points
* set reasonable trip points in thermal zone
* invert pwm-fan operating points and set shorter period to allow
less noisy operation of the PWM fan of the BPi-R3.
