[PATCH v3 1/3] [media] dvb_frontend: add S2X and misc. other enums

[Daniel Scheller <d.scheller.oss@gmail.com>]

From: Daniel Scheller <d.scheller@gmx.net>

Additional enums:
 * FEC ratios 1/4 and 1/3
 * 64/128/256-APSK modulations (DVB-S2X)
 * 15%, 10% and 5% rolloff factors (DVB-S2X)
 * 64K transmission mode (DVB-T2)

Add these enums to the frontend.h docs exceptions aswell (uapi docs are
updated separately).

Also, bump the DVB API version to 5.12 to make userspace aware of these
new enums.

Signed-off-by: Daniel Scheller <d.scheller@gmx.net>
---
v2 to v3:
- All new enum patches squashed into one commit
- DVB API bump to 5.12

Please take note of some additional things in the cover letter.
