1.  we only need to setup the GPIOs as outputs once
2.  there's no point in writing 0x40 to register 0x00 since that's the EEPROM

    and demod out of reset.  If you don't then the chip may not be properly

    out of reset).  This can result in probing failures.

Change 32bit NEC scancode format (used by Apple and TiVo remotes) to
encode the data with the correct bit order. Previously the raw bits were
used without being bit reversed, now each 16bit half is bit reversed
compared to before.

So for the raw NEC data:
  (LSB/First) 0xAAaaCCcc (MSB/Last)
(where traditionally AA=address, aa=~address, CC=command, cc=~command)

We now generate the scancodes:

  (MSB) 0x00AAaaCC (LSB) (extended NEC, address check wrong)
  (MSB) 0xaaAAccCC (LSB) (32-bit NEC, command check wrong)

Note that the address byte order in 32-bit NEC scancodes is different to
that of the extended NEC scancodes. I chose this way as it maintains the
order of the bits in the address/command fields, and CC is clearly
intended to be the LSB of the command if the TiVo codes are anything to
go by so it makes sense for AA to also be the LSB.

[media] nuvoton-cir: Don't touch PS/2 interrupts while initializing

There are reports[1] that on some motherboards loading the nuvoton-cir
disables PS/2 keyboard input. This is caused by an erroneous write of
CIR_INTR_MOUSE_IRQ_BIT to ACPI control register.

According to datasheet the write enables mouse power management event
interrupts which will probably have ill effects if the motherboard has
only one PS/2 port with keyboard in it.

The cir hardware does not need mouse interrupts to function and should
not touch them. This patch removes the illegal writes and registry
definitions.
