[U-Boot] [PATCH] davinci, mmc: fix gcc 4.6 build warnings

[Heiko Schocher]

Fix:
davinci_mmc.c: In function 'dmmc_wait_fifo_status':
davinci_mmc.c:72:7: warning: variable 'mmcstatus1' set but not used 
[-Wunused-but-set-variable]
davinci_mmc.c: In function 'dmmc_busy_wait':
davinci_mmc.c:89:7: warning: variable 'mmcstatus1' set but not used 
[-Wunused-but-set-variable]

Delete the unused variable.
