diff: trigger acpiac_refresh when acpibat notification

[YASUOKA Masahiko]

Hi,

Update the AC status when the battery notification is happened.
Because the AC status notification doesn't happen on some machines.
My vaio actually has this problem.

Also Linux is doing the same thing

https://github.com/torvalds/linux/blob/v6.4/drivers/acpi/ac.c#L165-L183

ok? comments?
