[media] rc: fix up and genericize some time unit conversions
The ene_ir driver was using a private define of MS_TO_NS, which is meant to be microseconds to nanoseconds. The mceusb driver copied it, intending to use is a milliseconds to microseconds. Lets move the defines to a common location, expand and standardize them a touch, so that we now have: MS_TO_NS - milliseconds to nanoseconds MS_TO_US - milliseconds to microseconds US_TO_NS - microseconds to nanoseconds Reported-by: David Härdeman <david@hardeman.nu> CC: Maxim Levitsky <maximlevitsky@gmail.com> Signed-off-by: Jarod Wilson <jarod@redhat.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
