[PATCH 1/2] [media] rc: Allow specifying properties for i2c IR's

[Mauro Carvalho Chehab]

Several I2C IR's only provide part of the IR protocol message (in general,
they provide only the command part). Due to that, some props fields need
to be specified.

[PATCH 2/2] [media] cx231xx: Don't register remote controls twice

[Mauro Carvalho Chehab]

There's a bug at cx231xx-input, where it were registering the remote controls
twice, one via ir-kbd-i2c and another directly. Fix it by registering it
only once.

While here, also fix Kconfig symbol change for IR core dependencies.
