pwm: stmpe: Rename variable pointing to driver private data

In all code locations but the probe function variables of type struct
stmpe_pwm * are called "stmpe_pwm". Align the name used in
stmpe_pwm_probe() accordingly. Still more as the current name "pwm" is
usually reserved for variables of type struct pwm_device *.
