drop: Ignore command version for FLASH_PROTECT command
The ec driver does not yet pass the command version properly from app
to the EC. This causes a failure when trying to read flashrom write
protect status (command 0x15).
The thing is that the command version is not even important for this
command, as it was never implemented differently.
As a quick fix - mark the command descriptor as supporting both
versions.
BRANCH=none
BUG=chromium:239197
TEST=manual
. on peach_pit (with fixed flashrom, coming under a separate fix):
# flashrom -p ec --wp-status
flashrom v0.9.4 : : on Linux 3.8.11 (armv7l), built with libpci 3.1.10, GCC 4.7.x-google 20130114 (prerelease), little endian
WP: status: 0x00
WP: status.srp0: 0
WP: write protect is disabled.
WP: write protect range: start=0x00000000, len=0x00000000
