Igor Opaniuk 8818b98e85 firehose: support VIP extension
This extends the Firehose protocol implementation to support the VIP
extension. It implements a state machine that counts the number of
packets sent, then injects the VIP table as the next RAW packet when
the Firehose programmer runs out of provided digests and needs a new table
of digests to validate the next packets. For example:

Packet 0: DigestsTableToSign.bin.mbn (53 digest + 1 digest of next table)
Packet 1: <configure>
Packet 2: <program>
Packet 3: ...
...
Packet 54: ChainedTableOfDigests0.bin (255 digests + digest of next table)
Packet 55: <program>
...
Packet 309: ChainedTableOfDigests1.bin

To enable VIP extension provide a path where previously generated VIP
tables are stored using "--vip-table-path" param:

$ qdl --vip-table-path "<vip-table-path>" prog_firehose_ddr.elf \
  rawprogram*.xml patch*.xml
