Right, I have added that to dts now, but the CI_HDRC_OVERRIDE_AHB_BURST
flag allows us to specify it from the platdata structure in the
ci_hdrc_msm.c file. As the value is zero for msm type controllers, I
left it out of the static definition of platdata because all the
non-initialized members of that structure are going to be zero anyway. I
can explicitly set it to zero to make it more clear if you like.
