Add support for the FE6600 tuner used on the DVB-T Hybrid board.
Add support for the Zarlink ZL10353 DVB-T demodulator, which supersedes the
MT352, used on the DViCO FusionHDTV DVB-T Hybrid and later model Plus boards.

This patch fixes the strange crashes I was seeing after using
bttv card, caused by a buffer overflow in bttv_risc_packed.
The instruction buffer size calculation contains two errors:
(a) a non-zero padding value can push the start of the next bpl
section to just before a page border, leading to more scanline
splits and thus additional instructions.
(b) the first DMA region can be smaller than one page, so there can
be a scanline split even if bpl*lines is smaller than PAGE_SIZE.
For example, consider the case where offset is 0, bpl is 2, padding
is 4094, lines is smaller than 2048, the first DMA region has size 1
and all others have size PAGE_SIZE, assumed to equal 4096.  Then
all bpl regions cross page borders and the number of instructions
written is 2*lines+2, rather than lines+2 (the current estimate).
With this patch the number of instructions for this example is
estimated to be 2*lines+3.
Also, the BUG_ON that was supposed to catch buffer overflows contained
a thinko causing it fire only if the buffer was overrun by a factor of
16 or more, so it fixes the the BUG_ON's (using sizeof rather than "4").

- fix temporary debug code by changing printk to dprintk at level 1.
- move CORE_IOCTL messages from level 1 to level 2.
- this should help with selective debugging,
  while not filling people's logs up during normal use.
