	Hi Simon, Magnus,

This patch series removes the bogus unit-addresses and reg properties
from the device nodes representing Cortex-A57/A53 cache controllers.

Note that the latter were added to remove warnings from dtc when using
W=1:

    Warning (unit_address_vs_reg): Node /cache-controller at 0 has a unit name, but no reg property

In hindsight, adding the reg properties turned out to be the wrong fix.
Indeed, the Cortex-A57/A53 cache controllers are integrated controllers,
and thus the device nodes representing them should not have
unit-addresses or reg properties.

This series does not have a runtime effect, as Linux doesn't rely much
on the properties of the cache-controller nodes.

After this patch has been accepted, I'll submit a similar series to fix
the DTS files for the Renesas arm32 SoCs.

Thanks for applying!
