firmware: cs_dsp: Handle long-offset data blocks

Browse source

Handle a new type of data block that has a 32-bit offset. These are
identical to the normal blocks except that the offset is now in the
32-bit field that was previously 'sr'.

A new file version of 3 indicates that it is mandatory to process
the long-offset blocks, so that older code without that support will
reject the file.

The original 'sr' field was never used by the driver so it has been
renamed offset32.
