util/sconfig: Add support for discontiguous FW_CONFIG fields
Sooner or later, some board was going to need extra FW_CONFIG bits for
a field that was already in production, so this patch adds support for
adding extra (unused) bits to a field.
The extra are appended via a syntax like:
`field FIELD_NAME START0 END0 | START1 END1 | START2 END2 ...`
and the suffixed bits are all treated as if they are contiguous when
defining option values.
BUG=b:185190978
TEST=Modified volteer fw_config to the following:
field AUDIO 8 10 | 29 29 | 31 31
option NONE 0
option MAX98357_ALC5682I_I2S 1
option MAX98373_ALC5682I_I2S 2
option MAX98373_ALC5682_SNDW 3
option MAX98373_ALC5682I_I2S_UP4 4
option MAX98360_ALC5682I_I2S 5
option RT1011_ALC5682I_I2S 6
option AUDIO_FOO 7
option AUDIO_BAR 8
option AUDIO_QUUX 9
option AUDIO_BLAH1 10
option AUDIO_BLAH2 15
option AUDIO_BLAH3 16
option AUDIO_BLAH4 31
end
which yielded (in static_fw_config.h):
