pwm: iqs620a: Prepare removing pwm_chip from driver data

Browse Source 
This prepares the driver for further changes that will drop struct
pwm_chip chip from struct iqs620_pwm_private. The only two functions
that make use of struct iqs620_pwm_private::chip (apart from the probe
function that is handled later when converting to pwmchip_alloc()) only
use the chip's device pointer. Introduce such a pointer in driver data
and use that instead.
