[U-Boot] [PATCH] ARM: DRA7xx: EMIF: Fix DLL_CALIB_CTRL register

[U-Boot] [PATCH] ARM: DRA7xx: EMIF: Fix DLL_CALIB_CTRL register

[Lokesh Vutla]

When DLL_CALIB_INTERVAL is set, an extra delay is added
which is not required and it consumes EMIF bandwidth.
So making the DLL_CALIB_CTRL[8:0]DLL_CALIB_INTERVAL bits to 0.

I missed updating on emif2 for beagle-x15. Ill send a v2 for this.
