hwmon: (sch5627) Use regmap for pwm map register caching
Accessing virtual registers is very inefficient, so pwm map values
should be cached when possible, else userspace could effectively do
a DOS attack by reading pwm map values in a while loop.
Use the regmap cache to cache those values.
Tested on a Fujitsu Esprimo P720.
