Always enable the pwr led and use the usr led for boot status indication.
Rename nodes in the dts, to match what is recommend in the devicetree
specification.
Increase the maximum spi frequency to 20MHz and drop the m25p,chunked-io
which isn't required on mt7621.
Use the BTN_0 keycode for the mode button. This board doesn't have any
wireless.
Use a more descriptive label for the reset button and the GPIO enabling
the usb vcc supply.
Use the beeper kernel module for the buzzer.
Fix the pinmux to switch only pins used as GPIOs to the GPIO function.
Add support for the PoE enable GPIO to the userspace. The PoE power
status can be read via GPIO7. Since OpenWrt doesn't have support for
reading inputs from userspace, prepare only the pinmux for the GPIO.

This patch adds support of MikroTik RouterBOARD 750Gr3, without the need
to reflashing the bootloader.
Installation through RouterBoot follows the usual MikroTik method
https://openwrt.org/toh/mikrotik/common
Since the image isn't compatible with RouterBOARD 750Gr3 installations
which have replaced the bootloader, the former used userspace boardname
is not added to the SUPPORTED_DEVICES, to prevent a brick while trying
to upgrade to the image with native support.

Specify firmware partition format by compatible string.
formats in ramips:
- denx,uimage
- tplink,firmware
- seama
It's unlikely but the firmware splitting might not work any longer for
the following boards, due to a custom header:
- EX2700: two uImage headers
- BR-6478AC-V2: edimax-header
- 3G-6200N: edimax-header
- 3G-6200NL: edimax-header
- BR-6475ND: edimax-header
- TEW-638APB-V2: umedia-header
- RT-N56U: mkrtn56uimg
But it rather looks like the uImage splitter is fine with the extra
header.
The following dts are not touched, due to lack of a compatible string in
the matching firmware splitter submodule:
- CONFIG_MTD_SPLIT_JIMAGE_FW
DWR-116-A1.dts
DWR-118-A2.dts
DWR-512-B.dts
DWR-921-C1.dts
LR-25G001.dts
- CONFIG_MTD_SPLIT_TRX_FW
WCR-1166DS.dts
WSR-1166.dts
- CONFIG_MTD_SPLIT_MINOR_FW

Use diag.sh version used for other targets supporting different leds
for the different boot states.
The existing led sequences should be the same as before.

Fix a typo in mt7621.dtsi compatible string. Disable spi, sdhci and pci
in mt7621.dtsi and enable the nodes in the indiviual board dts files.
The nodes require further device specific configuration anyway.
Remove the m25p80@0 spi child node from mt7621.dtsi and add the
chunked-io parameter to the individual board dts files. Fix the spi
flash compatible string for the WNDR3700V5.
Drop the mt7621-eval-board compatible string for all boards which are
not the eval board.
Drop the linux,modalias parameter from spi flash node.
Remove the xhci node from board files, it is already enabled in dtsi.
Disable xhci for boards not having usb ports populated.

The MikroTik hEX v3 (RB750Gr3) is a MT7621AT board which is similar to most MT7621 reference designs, it can be easily supported by this patch; however, the stock RouterBOOT bootloader has to be replaced by a MT7621 SDK U-Boot such as https://github.com/ndoo/RB750Gr3-U-Boot - U-Boot configured for the RB750Gr3 (16MiB SPI flash, 256MiB DDR3 RAM at 1200MHz).
RouterBOOT, the stock bootloader, does not initialize the UART and boots silently, making it preferable to replace it with a MT7621 SDK U-Boot with UART (57600 8N1) that supports HTTP, TFTP or serial upload of sysupgrade firmware and U-Boot.
Furthermore, RouterOS, the stock firmware, is contained in a proprietary modification of SquashFS without GPL sources; UART is also disabled in stock firmware.
The combination of LEDE firmware generated by this PR and MT7621 SDK U-Boot expects the printed MAC address to reside at offset `0xe000` of the factory partition (absolute offset is `0x4e000`); this is similar to the factory MAC address offset for several other MT7621 devices.
A 16MiB flash dump suitable for use with flashrom will be provided if/once this patch is accepted and binaries are built by LEDE buildbot. Alternatively, writing the U-Boot to the SPI flash starting at 0x0 offset and booting the board with serial console attached will allow TFTP, HTTP or serial upload of sysupgrade firmware.
