media: av7110: remove budget-patch driver

This patch removes the budget-patch stand alone driver only.
This patch does *not* remove the budget-patch support from the av7110
     (= dvb-ttpci) driver.
This patch does also *not* remove the support for the full-ts mod.

The budget-patch is an obsolete, experimental hardware modification, which
aimed to receive the whole transport stream of a transponder by bypassing
the av7110. This modification never worked reliably enough to be used in a
productive environment.
"almost no packet loss" [budget-patch.c #522] is still a packet loss.

The successor of the budget-patch is the full-ts mod, which is reliable.
The full-ts mod circuit is found on the never rev. 2.2 and 2.3 DVB-S
cards ex factory. The full-ts mod support is (only) in the av7110
(= dvb-ttpci) driver.

The budget-patch driver is a stand alone driver, which turns the card into
a budget card. It doesn't appear to be ever intended for the average user.
"Card is required to have loaded firmware to tune properly. Firmware can
be loaded by insertion and removal of standard av7110 driver prior to
loading this driver." [Kconfig]

There is support for the budget-patch in the av7110 (= dvb-ttpci) driver
too, which isn't affected by this patch.

The budget-patch is obsolete and replaced by the full-ts mod quiet a while
now. Remove the budget-patch driver left over from development.
