put_mtd_device() once the handle is no longer used.

OpenWRT requires a number of Perl modules to be installed. It wasn't checking on all of them.
This patch adds checks for Perl FindBin, File::Copy, File::Compare and Thread::Queue modules.
Failing to install these, will have the build break at some point. By adding these to the
prereq-build.mk script, they are checked on forehand.
Tested on a Fedora 33 and 34 (beta) that was freshly installed. Fedora appears to
break up Perl modules into small packages that need to be installed for the build to succeed.

The mode on the SGMII SerDes on the QCA9563 is 1000 Base-X by default.
This only allows for 1000 Mbit/s links, however when used with an SGMII
PHY in 100 Mbit/s link mode, the link remains dead.
This strictly has nothing to do with the SerDes calibration, however it
is done at the same point in the QCA reference U-Boot which is the
blueprint for everything happening here. As the current state is more or
less a hack, this should be fine.
This fixes the issues outlined above on a TP-Link EAP-225 Outdoor.

GPIO16 (tx-disable-gpios) should be governed by the SFP driver to enable

left as output high to ensure the SFP module is forced to transmit.
Tested on a RouterBOARD 922UAGS-5HPacD board, with a CISCO GLC-LH-SMD
1310nm module and an unbranded GLC-T RJ45 Gigabit module. PC=>router
iperf3 tests deliver 440/300 Mbps up/down, both via regular eth0 port
or SFP port with RJ45 module. Bridge between eth0 and eth1 delivers

The ZyXEL GS1900-8 is a 8 port switch without any PoE functionality or
SFP ports, but otherwise similar to the other GS1900 switches.
Specifications
--------------
* Device: ZyXEL GS1900-8 v1.2
* SoC: Realtek RTL8380M 500 MHz MIPS 4KEc
* Flash: Macronix MX25L12835F 16 MiB
* RAM: Nanya NT5TU128M8GE-AC 128 MiB DDR2 SDRAM
* Ethernet: 8x 10/100/1000 Mbit
* LEDs: 1 PWR LED (green, not configurable)
1 SYS LED (green, configurable)
8 ethernet port status LEDs (green, SoC controlled)
* Buttons: 1 on-off glide switch at the back (not configurable)
1 reset button at the right side, behind the air-vent
(not configurable)
1 reset button on front panel (configurable)
* Power 12V 1A barrel connector
* UART: 1 serial header (JP2) with populated standard pin connector on
the left side of the PCB, towards the back. Pins are labelled:
+ VCC (3.3V)
+ TX (really RX)
+ RX (really TX)
+ GND
the labelling is done from the usb2serial connector's point of
view, so RX/ TX are mixed up.
Serial connection parameters for both devices: 115200 8N1.
Installation
------------
Instructions are identical to those for the GS1900-10HP and GS1900-8HP.
* Configure your client with a static 192.168.1.x IP (e.g. 192.168.1.10).
* Set up a TFTP server on your client and make it serve the initramfs
image.
* Connect serial, power up the switch, interrupt U-boot by hitting the
space bar, and enable the network:
> rtk network on
* Since the GS1900-10HP is a dual-partition device, you want to keep the
OEM firmware on the backup partition for the time being. OpenWrt can
only boot off the first partition anyway (hardcoded in the DTS). To
make sure we are manipulating the first partition, issue the following
commands:
> setsys bootpartition 0
> savesys
* Download the image onto the device and boot from it:
> tftpboot 0x84f00000 192.168.1.10:openwrt-realtek-generic-zyxel_gs1900-8-initramfs-kernel.bin
> bootm
* Once OpenWrt has booted, scp the sysupgrade image to /tmp and flash it:
> sysupgrade /tmp/openwrt-realtek-generic-zyxel_gs1900-8-squashfs-sysupgrade.bin

Reduce spi-max-frequency for Xiaomi MI Router 4AG model
Xiaomi MI Router 4AG MTD uses two flash chips (no specific on router versions when produced from factory) - GD25Q128C and W25Q128BV.
These flash chips are capable of high frequency, but due to poor board design or manufacture process.
We are seeing the following errors in the linux kernel bootup:
`spi-nor spi0.0: unrecognized JEDEC id bytes: cc 60 1c cc 60 1c
spi-nor: probe of spi0.0 failed with error -2`
This causes the partitions not to be detected
`VFS: Cannot open root device "(null)" or unknown-block(0,0): error -6`
Then creates a bootloop and a bricked router.
The solution to limit this race condition is to reduce the frequency from 80 mhz to 50 mhz.
