V4L/DVB (4876): budget-ci IR: support EVIOCGPHYS

Browse source 
This patch adds a 'phys' string, of the same form as used by various other
DVB cards' IR drivers, for access by any program which uses the EVIOCPHYS
ioctl or may read /sys/class/input/*/phys (e.g. udev) to identify input
device nodes.
Taken from Darren Salt's dvb-ir patchset.
