spi: spi-mtk-nor: fix op checks in supports_op
commit a59b2c7c56bf7 ("spi: spi-mtk-nor: support standard spi properties")
tries to inverse the logic of supports_op when adding
spi_mem_default_supports_op check, but it didn't get it done properly.
There are two regressions introduced by this commit:
1. reading ops supported by program mode is rejected.
2. all ops with special controller routines are incorrectly further
checked against program mode.
This commits inverses the logic back:
1. check spi_mem_default_supports_op and reject unsupported ops first.
2. return true for ops with special controller routines.
3. check the left ops against controller program mode.
Fixes: a59b2c7c56bf7 ("spi: spi-mtk-nor: support standard spi properties")
