mmc: ftsdc010_mci: fix build error if CONFIG_FTSDC010_SDIO is not defined
The FTSDC010_DCR_FIFO_RST symbol is conditionally defined in <faraday/ftsdc010.h> and it is available available when CONFIG_FTSDC010_SDIO is enabled. However the actual driver code unconditionally uses the FTSDC010_DCR_FIFO_RST constant and this causes build error if CONFIG_FTSDC010_SDIO is not enabled. The following error happens when compiling for the adp-ag101 board: ftsdc010_mci.c: In function 'ftsdc010_request': ftsdc010_mci.c:178: error: 'FTSDC010_DCR_FIFO_RST' undeclared (first use in this function) ftsdc010_mci.c:178: error: (Each undeclared identifier is reported only once ftsdc010_mci.c:178: error: for each function it appears in.) The patch ensures that the FTSDC010_DCR_FIFO_RST symbol gets used only if CONFIG_FTSDC010_SDIO is defined. Compile tested only.
