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 <ag...@denx.de>
Acked-by: Heiko Schocher <h...@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
