Documentation: ad4130: format list of in_voltage-voltage_filter_mode_available modes 

Sphinx reports two warnings on sysfs documentation for AD4130 driver:

Documentation/ABI/testing/sysfs-bus-iio-adc-ad4130:2: WARNING: Unexpected indentation.
Documentation/ABI/testing/sysfs-bus-iio-adc-ad4130:2: WARNING: Block quote ends without a blank line; unexpected unindent.

These are due to misformatting of sinc* modes list. Format it with bullet
list. Since each entry spans multiple lines, separate each with a blank
line.

Description:
Reading returns a list with the possible filter modes.
"sinc4" - Sinc 4. Excellent noise performance. Long 1st
conversion time. No natural 50/60Hz rejection.
"sinc4+sinc1" - Sinc4 + averaging by 8. Low 1st conversion time.
"sinc3" - Sinc3. Moderate 1st conversion time. Good noise
performance.
"sinc3+rej60" - Sinc3 + 60Hz rejection. At a sampling frequency
of 50Hz, achieves simultaneous 50Hz and 60Hz
rejection.
"sinc3+sinc1" - Sinc3 + averaging by 8. Low 1st conversion time.
Best used with a sampling frequency of at least
216.19Hz.
"sinc3+pf1" - Sinc3 + Post Filter 1.
53dB rejection @ 50Hz, 58dB rejection @ 60Hz.
"sinc3+pf2" - Sinc3 + Post Filter 2.
70dB rejection @ 50Hz, 70dB rejection @ 60Hz.
"sinc3+pf3" - Sinc3 + Post Filter 3.
99dB rejection @ 50Hz, 103dB rejection @ 60Hz.
"sinc3+pf4" - Sinc3 + Post Filter 4.
103dB rejection @ 50Hz, 109dB rejection @ 60Hz.
