[PATCH] pinctrl: Iterate over u300_pmx_mask's in u300_pmx_endisable

[Rajendra Nayak]

Fix u300_pmx_endisable() to iterate over the list of 'bits' and
'mask' populated as part of u300_pmx_functions.mask[]

Linus W,
I am not sure if this is a right fix. I just stumbled
upon this while looking at the u300 pinmux driver
while I was writing one for OMAP. Maybe I am reading
the code completely wrong, and I don't even have a
way to test this, so its just compile tested with
u300_defconfig.
