Bug: LP#337943

LPIA Hardy Lum

Add sysfs control to enable or disable RTC Event Enable (RTC_EN) bit
of port ACPI PM1a_EVT_BLK because the BIOS overlooked this
functionality on the HP Mini. Disabling this before hibernate saves
several mAh.

Also tidied up whitespace/tab indentation and formatting.

Note that this extends the existing power management tweaks for this
particular netbook specific module.
