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 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.

Appears to be resolved by dropping zig-zag tuning and relying on
hardware only:

> szap-s2 -r -c 39.FTATV "1=Pgm1;Net1"
reading channels from file '39.FTATV'
zapping to 3 '1=Pgm1;Net1':
delivery DVB-S, modulation QPSK
sat 0, frequency 11140 MHz V, symbolrate 1425000, coderate 5/6, rolloff 0.35
vpid 0x0200, apid 0x0300, sid 0x0001
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
status 01 | signal ff80 | snr 0000 | ber 00000000 | unc 00000000 |
status 1f | signal ff80 | snr c199 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
status 1f | signal c040 | snr c199 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
status 1f | signal ff80 | snr c199 | ber 00000000 | unc 00000000 | FE_HAS_LOCK

Tuning to a weaker channel shows that the hardware recovers sync:

status 1f | signal fe40 | snr 5199 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
status 03 | signal fd40 | snr 5000 | ber 00000000 | unc 00000000 |

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

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.
