mvebu: backport upstream patch to fix COMPHY reset

Upstream commit [1] included in the Linux kernel version 6.2 was
backported to Linux kernels 6.1.4, 6.0.18. It should be possible that it
is going to be backported even to the 5.15 series, but before it happens,
let's include it here.

It was discovered that on SOC Marvell Armada 3720, which is using e.g.
Turris MOX, and if you are also using it with older ARM Trusted Firmware
v1.5, it is not possible to detect connected USB 3.0 devices, but they
are working just fine when connected with USB 2.0 cable. This patch
fixes it.
