[PATCH v2 07/10] mci: core: use CONFIG_MCI_WRITE, not CONFIG_BLOCK_WRITE

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

There's a more specific CONFIG_MCI_WRITE that's so far only used to
remove write support for in the Atmel MCI driver. We should use the same
symbol also to remove support in the MCI core instead of relying on the
CONFIG_BLOCK_WRITE option that's selected transitively by it.

v1 -> v2:
  - mention in commit message that MCI_WRITE selects BLOCK_WRITE
    indirectly
