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):
 FW_CONFIG_FIELD_AUDIO_MASK 0xa0000700
 FW_CONFIG_FIELD_AUDIO_OPTION_NONE_VALUE 0x0
 FW_CONFIG_FIELD_AUDIO_OPTION_MAX98357_ALC5682I_I2S_VALUE 0x100

@ -121,12 +121,48 @@ Each field is defined by providing the field name and the start and end bit mark
location in the bitmask. Field names must be at least three characters long in order to
satisfy the sconfig parser requirements and they must be unique with non-overlapping masks.
field <name> <start-bit> <end-bit> [option...] end
field <name> <start-bit> <end-bit> [option...] end
For single-bit fields only one number is needed:
field <name> <bit> [option...] end
A field definition can also contain multiple sets of bit masks, which can be dis-contiguous.
They are treated as if they are contiguous when defining option values. This allows for
extending fields even after the bits after its current masks are occupied.
field <name> <start-bit0> <end-bit0> | <start-bit1> <end-bit1> | ...
For example, if more audio options need to be supported:
field AUDIO 3 3
option AUDIO_0 0
option AUDIO_1 1
end
field OTHER 4 4
...
end
the following can be done:
field AUDIO 3 3 | 5 5
option AUDIO_FOO 0
option AUDIO_BLAH 1
option AUDIO_BAR 2
option AUDIO_BAZ 3
end
field OTHER 4 4
...
end
In that case, the AUDIO masks are extended like so:
#define FW_CONFIG_FIELD_AUDIO_MASK 0x28
#define FW_CONFIG_FIELD_AUDIO_OPTION_AUDIO_FOO_VALUE 0x0
#define FW_CONFIG_FIELD_AUDIO_OPTION_AUDIO_BLAH_VALUE 0x8
#define FW_CONFIG_FIELD_AUDIO_OPTION_AUDIO_BAR_VALUE 0x20
#define FW_CONFIG_FIELD_AUDIO_OPTION_AUDIO_BAz_VALUE 0x28
Each `field` definition starts a new block that can be composed of zero or more field options,
and it is terminated with `end`.
