[PATCH] update dvb frontend drivers

 - add budget driver as possible client of the ves1820 frontend driver
 - fix wrong include in sp887x.c frontend driver
 - fix wrong chip description in tda1004xh frontend driver
 - fixed detection of stv0299 if chip is in standby mode
 - change some #ifdef to #if, for easier debug enable/disable
 - ves1820: patch by Peter Bieringer: nicer log output
 - ves1820: allow PWM (tuner calibaration) value from EEPROM to be
   overridden on command line (based on patch by Peter Bieringer).  New
   module paramters: "pwm" (max 4 ints, range -1..0xff) and "verbose"
   (to print AFC value aftger tuning).
