spi: Add function to probe erase command opcode for all spi_master
Add a field, probe_opcode, to struct spi_master which points to a
function returning a bool by checking if a given command is supported by
the programmer in use. This is used for getting a whitelist of commands
supported by the programmer, as some programmers like ichspi don't
support all opcodes.
Most programmers use the default function, which just returns true.
ICHSPI and dummyflasher use their specialized function.
