[U-Boot] [PATCH] Revert "Revert "rockchip: rk3288: correct sdram setting""

[John Keeping]

The original commit was correct, except fot the priority of the mask
when extracting "bw" to calculate the SDRAM size.  Add the necessary
parentheses so that we can apply the original fix.

This reverts commit b525556e6325aa71427c0519f36247981cd444df.
