* 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.

Setup thermal zone, select pins and enabled drivers for I2C (on 26-pin
GPIO bank) and PWM (1x fan and 1x GPIO bank).

The GPIO used for the RST button is also used for PCIe-CLKREQ signal.
Hence it cannot be used as button signal if PCIe is also used.
Wire up WPS button to serve as KEY_RESTART in Linux and "reset" button
in U-Boot.

The Bananapi BPi-R3 is a development router board built around the
MediaTek Filogic 830 (MT7986A) SoC.
The board can boot either from microSD, SPI-NAND, SPI-NOR or eMMC.
Only either SPI-NAND or SPI-NOR can be used at the same time, also only
either microSD or eMMC can be used. The various storage options can be
selected using small SMD switches on the board.
Specs:
* MediaTek MT7986A (Filogic 830) 4x ARM Cortex A53
* 4T4R 2.4G 802.11bgnax (MT7975N)
* 4T4R 5G 802.11anac/ax (MT7975P)
* 2 GB DDR4 RAM
* 8 GB eMMC
* 128 MB SPI-NAND flash
* 32 MB SPI-NOR flash
* on-board MT7531 GbE switch
* 2x SFP+ (1 GbE / 2.5 GbE)
* 5x GbE network port
* miniPCIe slot (only USB 2.0 connected)
* uSIM slot (connected to miniPCIe interface)
* M.2 KEY-E PCIe interface (PCIe x2)
* microSD card interface
* 26 PIN GPIO

Working:
* all 4 boot methods incl. installation via U-Boot, sysupgrade, ...
* copper LAN and WAN ports
* SFP1 (connected to gmac1, eth1 in Linux)
* WiFi
* LEDs
* Buttons
* PSTORE/ramoops based dual-boot
Not Working (missing driver features):
* SFP2 (connected to MT7531 switch)
Untested:
* M.2/NGFF slot (PCIe x2)
