hpet: fix and cleanup persistence of interrupt status
There are several bugs in the handling of the ISR register:
- switching level->edge was not lowering the interrupt and
clearing ISR
- switching on the enable bit was not raising a level-triggered
interrupt if the timer had fired
- the timer must be kept running even if not enabled, in
order to set the ISR flag, so writes to HPET_TN_CFG must
not call hpet_del_timer()
