drivers/spi: support cmd opcode deduction for spi_crop_chunk()
spi_crop_chunk() currently supports deducting the command length
when determining maximum payload size in a transaction. Add support
for deducting just the opcode part of the command by replacing
deduct_cmd_len field to generic flags field. The two enums supported
drive the logic within spi_crop_chunk():
SPI_CNTRLR_DEDUCT_CMD_LEN
SPI_CNTRLR_DEDUCT_OPCODE_LEN
All existing users of deduct_cmd_len were converted to using the
flags field.
