[PATCH] net: phy: Add missing RGMII internal delay cases to vsc8541_config

Currently, vsc8541_config does not account for cases where RGMII
mode with internal delays on TX, RX or both are selected, even though
the device supports that functionality. Instead, it returns an
error when "rgmii-id", "rgmii-txid" or "rgmii-rxid" is selected
in its corresponding DT node.
Fix by adding missing RGMII internal delay modes to list of
fall-through cases so that when configured with modes "rgmii-id",
"rgmii-txid" or "rgmii-rxid", the internal delay registers get
updated correctly in vsc8531_vsc8541_clk_skew_config().
