[U-Boot] [PATCH v2 09/12] drivers/i2c/davinci_i2c.c: Fix GCC 4.6 warning

[Anatolij Gustschin]

Fix:
davinci_i2c.c: In function 'flush_rx':
davinci_i2c.c:81:6: warning: variable 'dummy' set but not used
[-Wunused-but-set-variable]

Signed-off-by: Anatolij Gustschin <agust at denx.de>
Acked-by: Heiko Schocher <hs at denx.de>

v2:
 - drop void cast since REG() is not a function call but
   expands to (*(volatile unsigned int *)(I2C_DDR))
   and thus we don't need to indicate that return value is ignored
   intentionally
