Horatiu Vultur 61243678c2 net: mscc: refactor mscc_miim 
Because all MSCC SoC use the same MDIO bus, put the implementation in
one common file(mscc_miim) and make all the other MSCC network drivers to
use these functions.

Horatiu Vultur 149468699e net: mscc: serval: Remove delay when serdes is configured 
When serdes configuration was written in hardware there was a delay
of 100ms to be sure that configuration was written. But the delay is not
needed because already the function serdes_write it is checking that the
operation finished.

Therefore remove the mdelay. This improves the speed of configuring the
network driver.
