[U-Boot] [PATCH] I2C: Exynos5: Reduce the Delay in s3c24x0 i2c driver

[Akshay Saraswat]

From: Alim Akhtar <alim.akhtar@samsung.com>

When no device is conneted on the i2c channel then i2c_probe command
was taking too much of time (around 3 mins) to come out from the loop.
Now reduced the delay loop to milisec value.
This is tested on smdk5250 only. As i dont have s3c24x0 boards, so i cannt
test on these baord.

conneted -> connected

dont -> don't, cannt -> can't?, baord -> board

And these two line(This is tested... board) should move under "---" line.
I think it is not a commit msg.
