[0/8] pwm: Get rid of pwm_[sg]et_chip_data()

Message

Hello,

the semantic of pwm_[sg]et_chip_data() overlaps with that of the
standard dev_[sg]et_drvdata() functions. Also as noted by George Stark
there is a problem in pwm-sti that relies on chipdata being available
even after a pwm_put (which clears chipdata).

To improve the situation this series converts all drivers that make use
of pwm chipdata to use well-known driver data instead and drop chipdata
support from the pwm framework.

Best regards
Uwe
