V4L/DVB (4688): Fix msp343xG handling (regression from 2.6.16)
The msp3430G and msp3435G models cannot do Automatic Standard Detection. So these should be forced to BTSC. These chips are early production versions for the msp34xxG series and are quite rare. The workaround for kernel 2.6.18 is to use 'standard=32' as msp3400 module option. Due to broken handling of the 'standard' option in 2.6.17 there is no workaround possible for that kernel.
