[PATCH 1/3] mceusb: add support for cx231xx-based IR (e. g. Polaris)

[Mauro Carvalho Chehab]

For now, it adds support for Conexant EVK and for Pixelview.
We should probably find a better way to specify all Conexant
Polaris devices, to avoid needing to repeat this setup on
both mceusb and cx231xx-cards.
