[PATCH v2 2/7] net: stmmac: Expand clock rate variables

[Jan Petrous (OSS)]

The clock API clk_get_rate() returns unsigned long value.
Expand affected members of stmmac platform data and
convert the stmmac_clk_csr_set() and dwmac4_core_init() methods
to defining the unsigned long clk_rate local variables.

Was it truncating before? Seems like that would justify a fixes tag if so...
