bd27fa44e1 usb: phy: generic: Don't use regulator framework for RESET line
Modelling the RESET line as a regulator supply wasn't a good idea
as it kind of abuses the regulator framework and also makes adaptation
code more complex.

Instead, manage the RESET gpio line directly in the driver. Update
the device tree binding information.

This also makes us easy to migrate to a dedicated GPIO RESET controller
whenever it becomes available.

4d175f340c usb: phy: nop: Defer clock prepare until PHY init
Since we only enable the PHY clock on init and the PHY init and shutdown
does not occur in atomitc context there is no need to prepare the clock
before it is enabled.  Move the clk_prepare() operations to go along
with the enables, allowing the clock to be fully idle when not in use.

53b6fc28ea usb: phy: phy-generic: export init functions
This patch exports the mostly generic functions so they can be used from
other phy driver instead of duplicating the code.

3fa4d7344b usb: phy: rename nop_usb_xceiv => usb_phy_gen_xceiv
The "nop" driver isn't a do-nothing-stub but supports a couple functions
like clock on/off or is able to use a voltage regulator. This patch
simply renames the driver to "generic" since it is easy possible to
extend it by a simple function istead of writing a complete driver.
