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.
