[PATCH v4 11/12] spi: mxic: Use spi_mem_generic_supports_op()

[Miquel Raynal]

This driver can be simplified a little bit by using
spi_mem_generic_supports_op() instead of the
spi_mem_default/dtr_supports_op() couple. The all_false boolean is
inverted to become a dtr boolean, which tacks if at least one of the
operation member uses dtr mode. The idea behind this change is to
simplify the introduction of the pipelined ECC engine.
