Controller version 0x0002450D has USB2 PHY RX sensitivity issues
that needs to be worked around by enabling phyrst-a-enable bit
in PHYRST_CFG register.

There is no way to distinguish between the controller version
before the device controller is started so we need to add this
DT property.
Maybe you should say "There is no way to know controller version
at host mode, but this workaround needs for both host and device
mode, so we have to add this DT property", the same for the comments
of your driver code patch.
I will reword it to

"There is no way to know controller version before device controller
is started and the workaround needs to be applied for both host and
device modes, so we add this DT property"
After apply it, feel free add:

Please apply above for device party commit log as well.
