[media] cx231xx: Fix i2c support at cx231xx-input

There was a bug at cx231xx-input, where it were registering the remote
controls twice, one via ir-kbd-i2c and another directly.
Also, the patch that added rc_register_device() broke compilation for it.

This patch fixes cx231xx-input by fixing the depends on, to point to the
new symbol, and initializing the scanmask via platform_data.

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