This patch fixes the bug in DMX_SET_BUFFER_SIZE for the demux.
Basically it resets read and write pointers to 0 in case they are
beyond the new size of the buffer.

Some DVB-S boards, i.e. with the SD1878 tuner, use a 4 MHz reference frequency.
This reqires a different setup of the clock PLL.
This patch adds an enum to the tda10086_config struct and sets the proper
values for the boards.
This patch also fixes the DVB-S section of the MD7134_BRIDGE_2

This patch fixes several issues on SCODE:
1) The extracting tool weren't generating the proper tags for SCODE. This
has almost no effect, since those tags shouldn't be used;
2) DIBCOM52 were using a wrong IF. It should be 5200, instead of 5700;
3) seek_firmware were wanting an exact match for firmware type. This is
wrong. As result, no SCODE firmware were loaded;
4) A few files were including the wrong file for seeking demod firmwares;
5) XC3028_FE_DEFAULT can be used, if user doesn't want to load a firmware.
However, this weren't documentated. This feature require more testing.

Before this patch, HVR900/HVR950 were incorreclty going back to analog. The
result is that only digital were working.
This patch provides the proper setup for analog/digital and tuner callback.
It also properly resets analog into a sane state at open().

Now, all registers will follow the same convension:
EM28XX_R<reg_number>_<reg_name>
This allows to associate a register with its value, and also with a canonical
name. Also, registers that are specific to a given chip were renamed accordingly,
as EM2800_foo (for 2800 only registers) or EM2880_foo (for registers that started
to appear on em2880).
