The armv7pmu driver doesn't support host/guest mode exclusion so
let's report this when set_event_filter is called with these
exclusion flags set.

The default implementation of regulator_set_load returns
REGULATOR_MODE_NORMAL, which is positive.
rt5663_i2c_probe should only do error handling when return value of
regulator_set_load is negative.
In this case, rt5663_i2c_probe should return error.
Also, consolidate err_irq into err_enable.
