[PATCH 7/7] ARM: S5PC210: I2C{3, 4, 5, 6, 7} device support

[kmpark@infradead.org (Kyungmin Park)]

From: Kyungmin Park <kyungmin.park@samsung.com>

S5PC210 support more I2C devices than previous SoCs.
And to prevent the wrong usage use the s5p prefix instead of s3c.

Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com>
