This patch converts the gp8psk module to use the S2API.
It pretends to be DVB-S2 capable in order to allow the various
supported modulations (8PSK, QPSK-Turbo, etc), and keep software
compatibility with the S2API patches for Mythtv and VDR.

The changeset 78aa52a159cf introduced a bug on em28xx: buffer setup should be
awaking xc3028. Instead, since we didn't specify the tuner mode, the device
were going to sleep, due to the lack of tuner mode when asking tuner to handle

The init_fw option was broken for the HVR-950q because we would call the reset
callback inside of dvb_attach() and the callback had not been setup yet.
Michael Krufky (who added the init_fw feature) says it's no longer required,
so just remove the option completely.
Thanks to user Zzeiss from #linuxtv chat for reporting the issue and

Don't operate under the assumption that every device that uses the em2820
default USB ID is a Prolink PlayTV USB. We have an eeprom hash, so use that,
since otherwise we cannot support other devices with the 2820 default USB ID
(such as the ADS Tech Instant TV USB USBAV-704)

tuner-xc3028 can be put to sleep to save power. However, if not properly
recovered from sleep, the device won't work. It is noticed that some
devices doesn't recover properly, so let's add a dump_stack() as a debug
option, to allow us to track when this happens.

Changes/fixes on em28xx dev->lock:
- em28xx_init_dev() were unlocking without a previous lock;
- some read ioctls need to lock after the removal of KBL, since a write
may be happening at the same time an ioctl is reading;
- keep the device locked during all device initialization;
- lock/unlock while reading/writing registers.

vidioc_try_fmt_vid_cap() just checks if a given resolution is supported.
It doesn't touch on struct em28xx device descriptor. so, there's no need
to lock.
While there, use unlikely() for those values that aren't likely to
occur.
