spi: SPI_QPIC_SNAND should be tristate and depend on MTD

SPI_QPIC_SNAND is the only driver that selects MTD instead of depending
on it, which could lead to circular dependencies.  Moreover, as
SPI_QPIC_SNAND is bool, this forces MTD (and various related symbols) to
be built-in, as can be seen in an allmodconfig kernel.

Except for a missing semicolon, there is no reason why SPI_QPIC_SNAND
cannot be tristate; all MODULE_*() boilerplate is already present.
Hence make SPI_QPIC_SNAND tristate, let it depend on MTD, and add the
missing semicolon.
