[PATCH 4/4] arm64: defconfig: Add M31 eUSB2 PHY config

From: Melody Olvera <melody.olvera at oss.qualcomm.com>

The Qualcomm SM8750 SoCs use an eUSB2 PHY driver different from the
already existing M31 USB driver because it requires a connection
to an eUSB2 repeater. Thus, for USB to probe and work properly on
the Qualcomm SM8750 SoCs, enable the additional driver.
