bq-paella: new device (BQ Aquaris X5 Cyanogen Edition)

Since BQ Aquaris X5 was released in two different flavours this is the device for Cyanogen Edition flavour. It is currently intended to be the mainline device while bq-picmt will be the downstream device

I updated the wiki page with details for both: https://wiki.postmarketos.org/wiki/BQ_Aquaris_X5_(bq-picmt)
