kernel: 5.10: Backport pending Armada 3720 comphy patches
Backport 5 pending patches [1] for Armada 3720 comphy driver and one patch for device tree, applied to mvebu-dt64, but pending to appear in Linus' tree [2]. These patches makes the driver work correctly even with older, buggy versions of TF-A firmware.

+Subject: [PATCH] Revert "ata: ahci: mvebu: Make SATA PHY optional for Armada
+ 3720"
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This reverts commit 45aefe3d2251e4e229d7662052739f96ad1d08d9.
+
+Armada 3720 PHY driver (phy-mvebu-a3700-comphy.c) does not return
+-EOPNOTSUPP from phy_power_on() callback anymore.
+
+So remove AHCI_HFLAG_IGN_NOTSUPP_POWER_ON flag from Armada 3720 plat data.
+
+AHCI_HFLAG_IGN_NOTSUPP_POWER_ON is not used by any other ahci driver, so
+remove this flag completely.
