mvebu: backport mvneta and comphy from linux 5.x

These patches backport support for the ARMADA 3700 COMPHY driver.
Also backported is the mvneta driver.  This will allow switching
the SGMII speed using SMC calls.  To support this you must update
the firmware using Marvells 18.12 version (this has now been
upstreamed).  The mvneta driver allows 2500basex and 2500baset.

+Subject: [PATCH] phy: fix build breakage: add PHY_MODE_SATA
+
+Commit 49e54187ae0b ("ata: libahci_platform: comply to PHY framework") uses
+the PHY_MODE_SATA, but that enum had not yet been added. This caused a
+build failure for me, with today's linux.git.
+
+Also, there is a potentially conflicting (mis-named) PHY_MODE_SATA, hiding
+in the Marvell Berlin SATA PHY driver.
+
+Fix the build by:
+
+    1) Renaming Marvell's defined value to a more scoped name,
+       in order to avoid any potential conflicts: PHY_BERLIN_MODE_SATA.
+
+    2) Adding the missing enum, which was going to be added anyway as part
+       of [1].
