ramips: add support for MikroTik hEX v3 (RB750Gr3)
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.

ramips: mt7621-dts: describe switch PHYs and adjust PHY muxing
Currently, the MT7530 DSA subdriver configures the MT7530 switch to provide
direct access to switch PHYs, meaning, the switch PHYs listen on the MDIO
bus the switch listens on. The PHY muxing feature makes use of this.
This is problematic as the PHY may be attached before the switch is
initialised, in which case, the PHY will fail to be attached.
Since commit 91374ba537bd ("net: dsa: mt7530: support OF-based registration
of switch MDIO bus") on mainline Linux, we can describe the switch PHYs on
the MDIO bus of the switch on the device tree.
When the PHY is described this way, the switch will be initialised first,
then the switch MDIO bus will be registered. Only after these steps, the
PHY will be attached.
Describe the switch PHYs on mt7621.dtsi and remove defining the switch PHY
on the SoC's mdio bus node. When the PHY muxing is in use, the interrupts
for the muxed PHY won't work, therefore delete the "interrupts" property on
the devices where the PHY muxing feature is in use.
