[media] pvrusb2: Provide more information about IR units to lirc_zilog and ir-kbd-i2c 

When registering an IR Rx device with the I2C subsystem, provide more detailed
information about the IR device and default remote configuration for the IR
driver modules.

Also explicitly register any IR Tx device with the I2C subsystem.
