hwmon: (aspeed-g6-pwm-tacho): Make use of devm_pwmchip_alloc() function

Browse Source 
This prepares the aspeed-g6-pwm-tacho driver to further changes of the
pwm core outlined in the commit introducing devm_pwmchip_alloc(). There
is no intended semantical change and the driver should behave as before.
