ath79: add support for kernel 5.4

Signed-off-by: David Bauer <[email protected]>
[refreshed]
Signed-off-by: Koen Vandeputte <[email protected]>

* 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.

++Required properties:

+Subject: [PATCH 20/33] MIPS: pci-ar724x: convert to OF
+
+With the ath79 target getting converted to pure OF, we can drop all the
+platform data code and add the missing OF bits to the driver. We also add
+a irq domain for the PCI/e controllers cascade, thus making it usable from
+dts files.

+
+This adds missing GMAC register definitions for the Qualcomm Atheros
+QCA955X series MIPS SoCs.
+
+They originate from the platforms U-Boot code and the AVM FRITZ!WLAN
+Repeater 450E's GPL tarball.

+Subject: [PATCH v4 1/2] spi: add driver for ar934x spi controller
+
+This patch adds driver for SPI controller found in Qualcomm Atheros
+AR934x/QCA95xx SoCs.
+This controller is a superset of the already supported qca,ar7100-spi.
+Besides the bit-bang mode in spi-ath79.c, this new controller added
+a new "shift register" mode, allowing faster spi operations.

+
+On AR934x this UART is usually not initialized by the bootloader
+as it is only used as a secondary serial port while the primary
+UART is a newly introduced NS16550-compatible.
+In order to make use of the ar933x-uart on AR934x without RTS/CTS
+hardware flow control, one needs to set the
+UART_CS_{RX,TX}_READY_ORIDE bits as other than on AR933x where this
+UART is used as primary/console, the bootloader on AR934x typically
+doesn't set those bits.
+Setting them explicitely on AR933x should not do any harm, so just
+set them unconditionally.

+Date: Tue, 16 Jun 2015 13:15:08 +0200
+Subject: [PATCH] phy/mdio-bitbang: prevent rescheduling during command
+
+It seems some phys have some maximum timings for accessing the MDIO line,
+resulting in bit errors under cpu stress. Prevent this from happening by
+disabling interrupts when sending commands.
