[PATCH 06/10] 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 its
parent CONFIG_BLOCK_WRITE option.
