ar8216: simplify PHY fixup/init

Move the PHY fixup call to the PHY init loop.
Use ar8xxx_has_gige in the PHY init instead of passing the gigE
capability via function parameter.

ar8216: Use generic hw_init from ar8236 for ar8216 too

We should make sure that also for ar8216 hw gets initialized.
For ar8216 hw_init is a dummy currently. The hw_init used for ar8236
should be generic enough to be usable with ar8216 too.
