[PATCH 4/6] i2c: stu300: do not request a specific clock name

[Linus Walleij]

From: Linus Walleij <linus.walleij at linaro.org>

We have used the default clock associated with the block
for a long time, only heuristics in the clock system has
made this work anyway. This needs to be done away with as
we start probing this driver and its clocks exclusively
from the device tree.

Hi Wolfram: seeking an ACK for this to take it through the
ARM SoC tree with the rest of my device tree clock patches
for U300.
