[net-next,v4,0/2] net: phy: add driver for MediaTek SoC built-in GE PHYs

Some of MediaTek's Filogic SoCs come with built-in gigabit Ethernet
PHYs which require calibration data from the SoC's efuse.
Despite the similar design the driver doesn't share any code with the
existing mediatek-ge.c, so add support for these PHYs by introducing a
new driver for only MediaTek's ARM64 SoCs.

As the PHYs integrated in the MT7988 SoC require reading the polarity
of the LEDs from the SoCs's boottrap also add dt-binding for that.

All LEDs are for now setup with default values, a follow up patch which
allows custom LED setups will be sent after the PHY LED framework is
more in shape.

Changes since v3:
 * fix spelling and reverse xmas tree
 * add dt-binding for mediatek,boottrap

Changes since v2:
 * remove everything related to PHY LEDs for now, LED support will
   be cleaned up and submitted once PHY LED framework is more ready

Changes since v1:
 * split-off SoC-specific driver from mediatek-ge.c as requested
 * address comments made by Heiner Kallweit
 * add pinctrl handling for PHY LED
 * remove calibration details not needed in production hardware
