phylib: add RGMII-ID mode to the Marvell m88e1111 PHY to fix broken ucc_geth 

Support for configuring RGMII-ID (RGMII with internal delay) mode on the
88e1111 and 88e1145.  Ucc_geth on MPC8360EMDS(the main user of ucc_geth)
is broken after changed to use phylib.  It is fixed by adding this
internal delay.

Also renamed 88e1111s -> 88e1111 (no references to an 88e1111s part were
found), and fixed some whitespace.
