commit ff96066e3171acdea356b331163495957cb833d0 upstream.

Both H_IS and H_IE needs to be set to receive H_RDY
interrupt

1. Assert H_IS to clear the interrupts during hw reset
and use mei_me_reg_write instead of mei_hcsr_set as the later
strips down the H_IS

2. fix interrupt disablement embarrassing typo
  hcsr |= ~H_IE -> hcsr &= ~H_IE;
this will remove the unwanted interrupt on power down

3. remove useless debug print outs
