The imx_obtain_fixed_clock() and imx_obtain_fixed_clock_hw() functions
behave pretty similarly, DRY and call one from another.

No functional changes intended.

NACK here. You're switching to a non "clk_hw" based variant that
should/would be removed in the near future.

In the future, we want the clock providers to not used "clk" based APIs.

Rule is, AFAIR, to use "clk" based APIs in clock consumer drivers only,
while using "clk_hw" based APIs in clock provider drivers only.

Right now, only the imx5 and vf610 clock provider drivers still use the
'clk' based API. Once those are switched to 'clk_hw' based, all the 'clk'
i.MX specific APIs will be removed for good.
