This patch is primarily a port of the integrated IR controller code in
cx23885/cx23888-ir.c. Right now, only the CX2388[57] AV core will
really try to set up IR. This IR support, by design, still requires the
bridge driver to do final IO pin mux configuration and setup of the IR
controller parameters.
For the CX2388[578] chips, enabling the AV Core for IR also starts
sending Audio and Video interrupts to the bridge driver. For
CX2388[578] chips audio and video interrupts are ignored and
acknowledged when they happen.
IR interrupt handling and status logging is exluded for the CX23888
which does not have an IR controller on the AV core.
Note that experimentation reveals that the IR irq enables on the
CX23885 have an inverted logic sense. The CX23887 likely suffers from
the same quirk. For these chips, those irq enable bits are handled
as interrupt disables.

This fixes some uneeded rebuilds under drivers/media/video after moving
the source tree. The makefiles used $(src) and $(srctree) for include
paths, which is unnecessary. Changed to use relative paths.
Compile tested, produces byte-identical code to the previous makefiles.

module
The cx25840 module requires external firmware in order to function,
so it must select FW_LOADER, but saa7115 and saa7129 do not require it.
This patch creates VIDEO_CX25840, and alters VIDEO_DECODER to select it.
