pwm: vt8500: Remove unnecessary OOM messages
The site-specific OOM messages are unnecessary, because they
duplicate the MM subsystem generic OOM message.

drivers/pwm: don't check resource with devm_ioremap_resource
devm_ioremap_resource does sanity checks on the given resource. No need to
duplicate this in the driver.

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

pwm: vt8500: Add polarity support
Add support to set polarity on PWM devices, allowing for inverted
duty cycles.
Also update the binding document to #pwm-cells = <3> to allow
passing the flags from devicetree.

pwm: vt8500: Register write busy test performed incorrectly
Correct operation for register writes is to perform a busy-wait
after writing the register. Currently the busy wait it performed
before, meaning subsequent register writes to bitfields may occur
before the previous field has been updated.
Also, all registers are defined as 32-bit read/write. Change
pwm_busy_wait() to use readl rather than readb.
Improve readability of code with defines for registers and bitfields.

pwm: vt8500: Ensure PWM clock is enabled during pwm_config
This patch corrects a bug reported by Peter Vasil.
When all PWMs are disabled, PWM module may be disabled during
calls to pwm_config. This patch enables/disables the clock in
pwm_config to ensure the module is active before register read/
writes.
