flash: Add command to get SPI flash chip info
Previously, there was no way to identify which flash chip was used by
the EC, for ECs using an external SPI flash. Now, 'ectool flashinfo'
will print more information about the SPI flash chip in these cases.
BUG=chrome-os-partner:56765
BRANCH=any EC with MEC1322 or NPCX still going through factory
TEST=define CONFIG_HOSTCMD_FLASH_SPI_INFO, then
'ectool flashspiinfo' on samus indicates no SPI flash info,
and prints additional info on chell and kevin. Without
the config defined, all platforms report no spi flash info.
CQ-DEPEND=CL:386368
