[PATCH v8 4/5] phy: move and rename Airoha PCIe PHY driver to dedicated directory

[Christian Marangi <ansuelsmth@gmail.com>]

To keep the generic PHY directory tidy, move the PCIe PHY driver for
Airoha AN7581 SoC to a dedicated directory.

Also rename the driver and add the relevant SoC name to the .c and .h
file in preparation for support of PCIe and USB PHY driver for Airoha
AN7583 SoC that use a completely different implementation and
calibration for PHYs and will have their own dedicated drivers.

The rename permits to better identify the specific usage of the driver
in the future once the airoha PHY directory will have multiple driver
for multiple SoC.

The config is changed from PHY_AIROHA_PCIE to PHY_AIROHA_AN7581_PCIE.
