support BMC boot flag valid bit clearing

Set/Get system boot options commands don't support
BMC boot flag valid bit clearing, add it.

Tested: it test by ipmi commands:
set BIOS boot option with parameter 3
ipmitool raw 0x00 0x08 0x03 xx
get boot option with parameter 3
ipmitool raw 0x00 0x09 0x03 0 0
for example:
ipmitool raw 0x00 0x08 0x03 2
no response, without error response
ipmitool raw 0x00 0x09 0x03 0 0
01 03 02
the third response datum is the value by setting boot option.
