[media] em28xx: input: use common work_struct callback function for IR RC key polling

Browse Source 
Remove em28xx_i2c_ir_work() and check the device type in the common callback
function em28xx_ir_work() instead. Simplifies em28xx_ir_start().
Reduces the code size with a minor performance drawback.
