[PATCH 4.2 09/30] net: dsa: bcm_sf2: Fix 64-bits register writes

[Greg Kroah-Hartman]

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

------------------

From: Florian Fainelli <f.fainelli@xxxxxxxxx>

[ 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.

Fixes: 246d7f773c13 ("net: dsa: add Broadcom SF2 switch driver")
