kernel: add Qualcomm SSDK driver

Qualcomm SSDK is driver for Qualcomm Atheros switches and PHY-s.

It is quite complicated and used by rest of the Qualcomm SDK stack for
anything switch or PHY related.

It is required for IPQ807x support as currently, there is no better driver
for the built-in switch or UNIPHY.

So, lets add the fixed-up version that supports kernel 5.15 for use on
ipq807x target until a better driver is available.

+Subject: [PATCH 03/11] SSDK: platform: use of_mdio_find_bus() to get MDIO bus
+
+Kernel has a generic of_mdio_find_bus() which can get the appropriate
+MDIO bus based on the DT node.
+So, drop the getting MDIO from platform data, which no longer works
+in 5.4 and later and use of_mdio_find_bus().

+Subject: [PATCH 07/11] qca807x: add a LED quirk for Xiaomi AX9000
+
+Xiaomi AX9000 has a single LED for each of 4 gigabit ethernet ports that
+are connected to QCA8075, and that LED is connected to the 100M LED pin.
+
+So, by default it will only work when in 10 or 100Mbit mode, this is quite
+annoying and makes no sense(If they have connected it to the 1000Mbit LED
+pin then it would have worked for 10/100 by default as well).
+
+So, to solve this add a check for system compatible as we cant parse if
+from DTS in any other way and set the 100M LED to blink on 1000Base-T
+as well.

+
+AX3600 requires the same LED quirk so that PHY LED-s will blink even
+once Linux resets the PHY.
+
+So, just check for its compatible.
