net: stmmac: rk: use rk_encode_wm16() for RGMII clocks

Browse source

As all of the RGMII clock selection bitfields (gmii_clk_sel) use the
same encoding, parameterise this by providing the bitfield mask in
the BSP private data.

This is the last user of GRF_FIELD_CONST(), so remove that definition
as well.

One additional change is for RK3328 - as only gmac2io supports RGMII,
only initialise the mask for this instance.
