no functional changes, just renaming the function
in order to make it slightly clearer what it should
be used for, also matching the driver name.

instead of having each user of generic phy find
out about its own resources and pass it to the
core layer, have th core layer itself figure that
out. It's as simple as moving a piece of code
around. This fixes a big regression caused during
the merge window where am335x-based platforms
wouldn't be able to probe their PHY driver.

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.

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.

This patch exports the mostly generic functions so they can be used from
other phy driver instead of duplicating the code.
