net: dsa: bcm_sf2: Fix 64-bits register writes
[ 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")
