Reimplements read optimization on top of spi-mem. Similar to
what 461-spi-ath79-add-fast-flash-read.patch used to do with
the dropped flash read interface.
It accelerate only fast-read op reading flash directly from
memory mapped region. 'm25p,fast-read' must be set in order
to use the new spi-mem.
It improved read speed up to 3x on old devices (tplink,tl-wr2543-v1)
while no speed improvement was noticed on newer devices like
(tplink,archer-c7-v2).

The ag71xx driver from Linux 5.4 currently has various shortcomings
when used with OpenWrt compared to our downstream version.
For example, the upstream driver does not support modifying the ethernet
clock and configuring RGMII delays on the MAC side.
While we should certainly switch to the upstream driver, the amount of
necessary patches would make it cumbersome to work with. It's also
highly likely we won't be able to finish patching the upstream driver in
time for a Linux 5.4 release.
Tested on Siemens WS-AP3610.

Patch 0061-tty-serial-ar933x-uart-rs485-gpio.patch wasn't included
when adding support for kernel 5.4. Re-add it and refresh patches.

This removes the assignment of setup and cleanup functions for the ath79
target. Assigning the setup-method will lead to 'setup_transfer' not
being assigned in spi_bitbang_init.
Also drop the redundant cleanup assignment, as this also happens in
spi_bitbang_init.

* Fix some bugs in the driver
* Add missing clock and reset references in dts
* Rename mdio-bus to mdio so the driver find it

* Sync the patches with the changes done for kernel 4.19
* Use KERNEL_TESTING_PATCHVER
* Refresh the configuration
* Fix multiple compile bugs in the patches
* Only add own ag71xx files for kernel 4.19 and use upstream version for
5.4.
