[PATCH v2] ARM: dts: aspeed: zaius add reg field to pca9541a i2c mux

[Xo Wang]

It looks like this issue is fixed in v4.9: https://lkml.org/lkml/2016/8/15/569

The cover letter to that patchset also mentions adding an unused "reg"
property as a workaround. I had probably copied and pasted the pca9541
bindings without "reg" to the Zaius dts without reading the rest of
the notes. Oops.

Should we backport that patchset and/or wait for the next OpenBMC kernel rebase?

Emily: can you test whether the "reg" property is still necessary if
you backport those patches?

cheers
