[PATCH 2/6] macb: fix clock probing with DT

[Sam Ravnborg]

With DT enabled the following was logged:

   macb fffbc000.ethernet: no macb_clk
   macb fffbc000.ethernet: probe failed: Invalid argument

The clock probed was with the name used in a non-DT setup.
Fix so we use a proper name ("pclk") with DT, and keep
current fuctionality without DT.
