The PCS IRQ enable/disable procedures have been utilized in the framework
of the PHYLINK PCS enable/disable callbacks. Since a generic STMMAC
PHYLINK PCS implementation is about to be introduced let's move the
procedures into the dedicated DW GMAC and DW QoS Eth HW-abstraction
methods. These methods will be called from the PCS enable/disable
functions defined in the stmmac_pcs.c in the DW MAC-independent manner.
