Subject: [PATCH 19/90] sunxi: mmc: Move header to the driver directory
The MMC controller driver is (and ought to be) the only user of these
register definitions. Put them in a header next to the driver to remove
the dependency on a specific ARM platform's headers.
Due to the sunxi_mmc_init() prototype, the file was not renamed. None of
the register definitions were changed.
