V4L/DVB (13680): ir: use unsigned long instead of enum

When preparing the linux-next patches, I got those errors:

include/media/ir-core.h:29: warning: left shift count >= width of type
In file included from include/media/ir-common.h:29,
                 from drivers/media/video/ir-kbd-i2c.c:50:
drivers/media/video/ir-kbd-i2c.c: In function ‘ir_probe’:
drivers/media/video/ir-kbd-i2c.c:324: warning: left shift count >= width of type

Unfortunately, enum is 32 bits on i386. As we define IR_TYPE_OTHER as 1<<63,
it won't work on non 64 bits arch.
