tablet-x86uefi: add ath6kl fw, enable i2c TS, drop phoc scaling (MR 4185)

- ath6kl fw is used by some tablets (e.g. baytrail)

- Add support for i2c touchscreens in initramfs, which enables FDE
  support for tablets that have i2c touchscreens.

- Drop phosh subpackage / phoc.ini. Forcing 1X scaling is wrong on some
  tablets... Phoc/phosh is capable of detecting screen scaling, if it's
  wrong on a tablet then a patch should be submitted upstream to fix it.
