net: pcs: xpcs: add xpcs_destroy_pcs() and xpcs_create_pcs_mdiodev()

Browse Source 
Provide xpcs create/destroy functions that return and take a phylink_pcs
pointer instead of an xpcs pointer. This will be used by drivers that
have been converted to use phylink_pcs pointers internally, rather than
dw_xpcs pointers.

As xpcs_create_mdiodev() no longer makes use of its interface argument,
pass PHY_INTERFACE_MODE_NA into xpcs_create_mdiodev() until it is
removed later in the series.
