ichspi: Probe opcode in POSSIBLE_OPCODES[] as well

ich_spi_send_command() and ich_spi_send_multicommand() will overwrite
the "Sector erase" opcode with the opcode for command via
reprogram_opcode_on_the_fly(), but not restore it, causing the "Sector
erase" opcode may get lost after sending commands, leaving only "Bulk
erase" opcode which erase the whole chip available.

In the mean time, ich_spi_probe_opcode() used not to report opcodes in
POSSIBLE_OPCODES[] but not in curopcodes->opcode[] as supported.

Now, if the opcode being probed is not in curopcodes->opcode[] but in
POSSIBLE_OPCODES[], it will be programmed on-the fly, and reported as
supported if successfully programmed.
