Use the new helper devm_platform_ioremap_resource() which wraps the
platform_get_resource() and devm_ioremap_resource() together, to
simplify the code.

Currently the function pwm_imx27_get_state() of enables the clocks once
unconditionally at the start, a second time if the PWM is enabled and
disables unconditionally at the end.
Simplify that to enable once at the start and disable conditionally at
the end.

"ret" only holds zero and negative error codes. It needs to be signed
for the error handling to work.

The two PWM implementations called v1 (for i.MX1 and i.MX21) and v2 (for
i.MX27 and later) have nothing in common apart from needing two clocks
named "per" and "ipg" and being integrated in a SoC named i.MX.
So split the file containing the two disjunct drivers into two files and
two complete separate drivers.
