====================
net: phy: at803x: Update delays for RGMII modes

Peter[1] reported that patch cd28d1d6: ("net: phy: at803x: Disable
phy delay for RGMII mode") caused regression on am335x-evmsk board.
This board expects the Phy delay to be enabled but specified RGMII mode
which refers to delays being disabled. So fix this by disabling delay only
for RGMII mode and enable for RGMII_ID and RGMII_TXID/RXID modes.

While at it, as pointed by Dave, don't inline the helpers.
