Subject: [PATCH] usb: ehci-platform: switch over to shared reset

The recent update in the reset subsystem requires all reset consumers
to be explicit when requesting reset lines.  For detail, see the log
of commit 3c35f6edc09b ("reset: Reorder inline reset_control_get*()
wrappers").

The devm_reset_control_get_optional() is deprecated, and falls into
the _exclusive variant during the migration, but the reset control
in this driver is apparently shared-tolerate.  Besides, this driver
is for generic platforms, so actually should be able to work with a
shared reset line.
