When a front-end is disabled, card drivers that use it are compiled with
a stub version of the front-end's attach function.  This way they have no
references to the front-end's code and don't need it to be loaded.
If a card driver is compiled into the kernel, and a front-end is a
module, then that front-end is effectively disabled wrt the card driver. 
In this case, the card driver should get the stub version.  This was not
happening.
The stub vs real attach function selection is changed so that when the
front-end is a module the real attach function is only used if the card
driver is a module as well.  This means a module front-end will be
supported by card drivers that are modules and not supported by card
drivers compiled into the kernel.

This driver was originally in budget-av.c, however I have extracted it into
a seperate file to permit reuse.
I also reworked the code to make it maintainable. I then examined the KNC1
windows drivers and rewrote the code in order to configure the PLL as they
do. This solves a lot of reported tuning problems.

1) It sets LNBDCPol differently based on the card type. Now it should
work properly for both the kworld and geniatech cards.
2) It stops returning an error for the SEC_VOLTAGE_OFF voltage command
(the cx88-dvb level handles the actual voltage on/off, but it still
passes the ioctl down to the cx24123 level, which previously rejected
the OFF as invalid so the ioctl would report failure)

Typical wiring of MT352 and ZL10353 based tuners differs from dvb-pll's
expectation that the PLL is directly accessible.  On these boards, the
PLL is actually hidden behind the demodulator, and as such can only be
accessed via the demodulator's interface.  It was failing to communicate
with the PLL during an attach test and subsequently not connecting the
tuner ops.
By passing a NULL I2C bus handle to dvb_pll_attach, this accessibility
check can be bypassed.  Do this for the affected boards.  Also fix a
possible NULL dereference at sleep time, which would otherwise be
exposed by this change.
