devm_ioremap_resource does sanity checks on the given resource. No need to
duplicate this in the driver.

PWM_ID_BASE() is not used after convert to PWM framework, remove it.
Also update driver_data field of struct platform_device_id accordingly.

clk_enable/clk_disable maintain an enable_count, clk_prepare and clk_unprepare
also maintain a prepare_count. These APIs will do prepare/enable when the first
user calling these APIs, and do disable/unprepare when the corresponding counter
reach 0. Thus We don't need to maintain a clk_enabled counter here.

Convert all uses of devm_request_and_ioremap() to the newly introduced
devm_ioremap_resource() which provides more consistent error handling.

CONFIG_HOTPLUG is going away as an option so __devexit is no

Make sure the duty-cycle and period passed in are not negative. This
should eventually be made implicit by making them unsigned. While at
it, the drivers' .config() implementations can have the equivalent
checks removed.

If the pwmchip_remove() call fails, propagate the error to the driver's
remove callback. This is required to prevent the module from being
unloaded if a PWM provided by the driver is still in use.

This commit moves the PXA PWM driver to the drivers/pwm subdirectory and
converts it to use the new PWM framework.
