Sylvain Munaut 0297cd029b fw/tuner_e4k: Experimental new init sequence 
More complete ... Tries to bring up the e4k to a usable
state all at once.

Sylvain Munaut b0baaab491 uart_cmd: Add support for read commands with arguments 
The syntax is really not obvious, but at least the implementation
is simple ...

Sylvain Munaut 24c3a9a196 fw/tuner_e4k: DC offset table gen doc fixes 
No we don't need to wait. I checked if the value ever changed after
the first read and it doesn't. Other e4k drivers don't wait either.

Sylvain Munaut eeaa36a1fb fw/tuner_e4k: Fix the array_size of the filter fw settings. 
This was causing the array length to be '1' and so we always
took the first possible setting (the widest) ...

Certainly not good when you only have a 500 kHz sample rate.

Sylvain Munaut 60d88b6ed2 tuner_e4k: Fix closest_arr_idx 
The previous method tried to do clever stuff assuming the sequence is
sorted. Unfortunately:

1) this didn't really find the 'closest' match
2) this didn't work for the first or last interval
3) this didn't work for freq slightly above or below the last/first freq

All in all, it's easier to try them all.
