This reverts 18bc174481 and changes
the code at img-ir-nec.c to use the order used by the other NEC decoders.
The original patch ignored the fact that NEC32 scancodes are generated not
only in the NEC raw decoder but also directly in some drivers. Whichever
approach is chosen it should be consistent across drivers and this patch
needs more discussion.
Furthermore, I'm convinced that we have to stop playing games trying to
decipher the "meaning" of NEC scancodes (what's the customer/vendor/address,
which byte is the MSB, etc).

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) 0x0000AACC (LSB) (normal NEC)
(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.
The TiVo keymap is updated accordingly.

A pending cleanup will mean that module.h won't be implicitly
everywhere anymore. Make sure the modular drivers in clocksource
are actually calling out for <module.h> explicitly in advance.
