thermal/drivers/hisi: Remove costly sensor inspection
The sensor is all setup, bind, resetted, acked, etc... every single second.
That was the way to workaround a problem with the interrupt bouncing again and
again.
With the following changes, we fix all in one:
- Do the setup, one time, at probe time
- Add the IRQF_ONESHOT, ack the interrupt in the threaded handler
- Remove the interrupt handler
- Set the correct value for the LAG register
- Remove all the irq_enabled stuff in the code as the interruption
handling is fixed
- Remove the 3ms delay
- Reorder the initialization routine to be in the right order
It ends up to a nicer code and more efficient, the 3-5ms delay is removed from
the get_temp() path.
