acpi_ec: changes in communication with hardware
Short description of the changes:
- attempt to retry some commands for which it is possible (read, query)
- always make a short sleep before checking EC status in polled mode
- periodically poll EC status in interrupt mode
- change logic for detecting broken interrupt delivery and falling back
to polled mode
- check that EC is ready for input before starting a new command, wait
if necessary
