The current condition is always true, so everything uses
LOGICAL_DEV_CIR_REV2 (8). It should be that Fintek products
0x0408(F71809) and 0x0804(F71855) use logical device
LOGICAL_DEV_CIR_REV1 (5) and other chip ids use logical device 8.

In other words, this fixes hardware detection for 0x0408 and 0x0804.

An early registration of an ISR was causing a crash to several users (for
example, with the ite-cir driver: http://bugs.launchpad.net/bugs/972723).
The reason was that IRQs were being triggered before a driver
initialisation was completed.

This patch fixes this by moving the invocation to request_irq() and to
request_region() to a later stage on the driver probe function.

There was a missing lock in fintek_suspend. Without the lock, its
possible the system will be in the middle of receiving IR (draining the
RX buffer) when we try to disable CIR interrupts.

This is a new driver for the Fintek LPC SuperIO CIR function, in the
Fintek F71809 chip. Hardware and datasheets were provided by Fintek, so
thanks go to them for supporting this effort.

This driver started out as a copy of the nuvoton-cir driver, and was
then modified as needed for the Fintek chip. The two share many
similaries, though the buffer handling for the Fintek chip is actually
nearly identical to the mceusb buffer handling, so the parser routine is
almost a drop-in copy of the mceusb buffer parser (a candidate for being
abstracted out into shared code at some point).

This initial code drop *only* supports receive, but the hardware does
support transmit as well. I really haven't even started to look at
what's required, but my guess is that its also pretty similar to mceusb.
Most people are probably only really interested in RX anyway though, so
I think its good to get this out there even with only RX.

(Nb: there are also Fintek-made mceusb receivers, which presumably, this
chip shares CIR hardware with).

This hardware can be found on at least Jetway NC98 boards and derivative
systems, and likely others as well. Functionality was tested with an
NC98 development board, in-kernel decode of RC6 (mce), RC5 (hauppauge)
and NEC-ish (tivo) remotes all successful, as was lirc userspace decode
of the RC6 remote.
