4.2-stable review patch. If anyone has any objections, please let me know.

From: Florian Fainelli <f.fainelli@gmail.com>
[ Upstream commit 03679a14739a0d4c14b52ba65a69ff553bfba73b ]
The macro to write 64-bits quantities to the 32-bits register swapped the value and offsets arguments, we want to preserve the ordering of the arguments with respect to how writel() is implemented for instance: value first, offset/base second.
