Title:
  hw/mc146818: error reading RTC_HOURS_ALARM

Status in QEMU:
  Expired

Bug description:
  get_next_alarm() doesn't read the RTC_HOURS_ALARM field correctly.

  - Bit 7 must be masked before conversion from BCD.
  - Care must be taken to check the don't care condition before masking.
  - The PM bit must be read from RTC_HOURS_ALARM, not from RTC_HOURS (as is 
done in convert_hour()).

  Seen in commit e376a788ae130454ad5e797f60cb70d0308babb6.
