Hi,

A lot of stmmac platform code which sets the transmit clock is very
similar - they decode the speed to the clock rate (125, 25 or 2.5 MHz)
and then set a clock to that rate.

The DWMAC core appears to have a clock input for the transmit section
called clk_tx_i which requires this rate.

This series moves the code which sets this clock into the core stmmac
code.

Patch 1 adds a hook that platforms can use to configure the clock rate.
Patch 2 adds a generic implementation.
The remainder of the patches convert the glue code for various platforms
to use this new infrastructure.

Changes since RFC: fix build errors, add Thierry Reding's r-b. More
platform glue conversions.
