In the past few years, we have received several reports about SPI
Flash not working properly. This is caused by excessively fast
clock frequency. It's really annoying to fix them one by one. Let's
reduce these aggressive frequencies to 50 MHz. This is a safe and
suggested value in the vendor SDK.

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.

- Installation:
1. Download the OpenWrt initramfs-image.
Place it into a TFTP server root directory and rename it to openwrt.img
Configure the TFTP server to listen at 192.168.0.5/24.
3. Connect to the serial console.
Attach power and interrupt the boot procedure when prompted (type `tpl`).
Credentials are admin / 1234
4. Configure U-Boot for booting OpenWrt from ram
$ tftpboot
$ bootm
5. Transfer the OpenWrt sysupgrade image to the device.
- LTE:
In order to setup the wwan0 interface:
1. Add a `qmi` proto interface under `/etc/config/network`, e.g.:
```
config interface 'wwan0'
option device '/dev/cdc-wdm0'
option proto 'qmi'
option pincode 'XXXX'
option apn 'your_isp_apn'
```
2. Add `wwan0` interface to the `wan` firewall zone
3. `/etc/init.d/network restart`
