V4L/DVB (9926): em28xx: Fix a bug that were putting xc2028/3028 tuner to sleep

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
VIDIOC_S_FREQUENCY:

xc2028 0-0061: Device is Xceive 3028 version 1.0, firmware version 2.7
xc2028 0-0061: divisor= 00 00 14 d0 (freq=83.250)
xc2028 0-0061: Putting xc2028/3028 into poweroff mode.
xc2028 0-0061: Printing sleep stack trace:

V4L/DVB (9928): Convert GP8PSK module to use S2API

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.

V4L/DVB (9936): cx18: Disable locking of Video and Audio PLL for analog captures

Disable AV_LOCK, locking of audio PLL to video PLL in the cx18-av-core for
analog captures.  It seems to have adverse effects on captures from
SVideo and CVBS sources with current clock & crystal settings in the driver.

Many thanks to Jeff Campbell and Mike Bradley for reporting this problem,
and suggesting the solution and performing extensive testing to support their
suggestion.

V4L/DVB (9937): cx18: Use a consistent crystal value for computing all PLL parameters

Use a consistent crystal value of 28.636360 MHz for computing all PLL
parameters so clocks don't have relative error due to assumed crystal
value mismatches.  Also aimed to have all PLLs run their VOCs at close to
400 MHz to minimze the error of these PLLs as frequency synthesizers. Also
set the VDCLK and AIMCLK PLLs to sane values before the APU and CPU firmware
are loaded.  Also fixed I2S Master clock dividers.

Many thanks to Mike Bradley and Jeff Campbell for reporting this problem and
suggesting the solution, researching and experimenting, and performing
extensive testing to support their suggested solution.
