Other drivers use lowercase hexadecimal literals, so convert the IQS620a
driver to do the same for consistency.

5bc5d99f1f pwm: iqs620a: Use 64-bit division 
The PWM framework is going to change the PWM period and duty cycles to
be 64-bit unsigned integers. To avoid build errors on platforms that do
not natively support 64-bit division, use explicity 64-bit division.
