V4L/DVB: ir-core: change duration to be coded as a u32 integer
This patch implements the agreed upon 1:31 integer encoded pulse/duration struct for ir-core raw decoders. All decoders have been tested after the change. Comments are welcome. Signed-off-by: David Härdeman <david@hardeman.nu> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
