[PATCH] dvb: Update DVB frontend drivers 

From: Michael Hunold <hunold@linuxtv.org>

alps_tdmb7, cx24110: use correct delay values, don't divide by HZ when using
dvb_delay(), found by Artur Skawina

alps_tdmb7: set FE_HAS_LOCK only when all low-order bits are valid

mt312: patch for the mt312 module, targeting the VP310: reduced heat,
implement "auto" inversion mode, remove debugging verbosity, add module
parameter for debugging (Augusto Cardoso)

nxt6000: code review and beautification, use per i2c-adapater void pointer
for private data in nxt_attach() / nxt_detach, fix frontend private data
handling.  patch by Mikael Rosbacke <rosbacke at nada.kth.se>

sp887x: firmware loader implementation contributed by Martin Stubbs, C99
comile fixes by Wolfgang Thiel

stv0299: Added new module parameter to choose between BER and UCBLOCKs error
monitoring since the STV0299 can't do both at once, Added modifications based
on the recommended settings in the SU1278 datasheet.

tda1004x: remove FE_CAN_INVERSION_AUTO

ves1820:completed nokia board support, increased some delays to get constant
results,set default pwm value to 0x48 for boards which don't have an eeprom

Driver for the Microtune 7202D Frontend
*/
/*
This driver needs a copy of the Avermedia firmware. The version tested
is part of the Avermedia DVB-T 1.3.26.3 Application. If the software is
installed in Windows the file will be in the /Program Files/AVerTV DVB-T/
directory and is called sc_main.mc. Alternatively it can "extracted" from
the install cab files. Copy this file to /etc/dvb/sc_main.mc.
With this version of the file the first 10 bytes are discarded and the
next 0x4000 loaded. This may change in future versions.
