Revert "usb: dwc3: meson-g12a: fix shared reset control use"

This reverts commit 8d41a1f17662e9951a187cd1a766f2e36a42d821.

This commit breaks USB on meson-gxl-s905x-libretech-cc. Reverting
the change solves the issue.

In fact, according to the reset framework code, consumers must not use
reset_control_(de)assert() on shared reset lines when reset_control_reset
has been used, and vice-versa.

Moreover, with this commit, usb is not guaranted to be reset since the
reset is likely to be initially deasserted.

Reverting the commit will bring back the suspend warning mentioned in the
commit description. Nevertheless, a warning is much less critical than
breaking dwc3-meson-g12a USB completely. We will address the warning
issue in another way as a 2nd step.
