From: Grygorii Strashko <grygorii.strashko@ti.com>

commit 316b429459066215abb50060873ec0832efc4044 upstream.

Now phy-gmii-sel will disable MAC TX internal delay for PHY interface mode
"rgmii-rxid" which is incorrect.
Hence, fix it by enabling MAC TX internal delay in the case of "rgmii-rxid"
mode.
