Coverity warns about the risk of unintended sign-exension in some of the
calculations in spmi_arb.c. While the actual numbers used are small
enough that this cannot happen in practice, it's still a good idea to
clean them up by explicitly making the constants used unsigned.

With an open source SPMI driver we can now remove qtiseclib involvement
in reset and shutdown handling by setting the required registers
directly.

This patch adds a very rudimentary driver for the SPMI arbitrator used
to access the PMIC. It doesn't support all the controller's actual
arbitration features, so it should probably not be used concurrently
with a running kernel (and it's also not optimized for performance). But
it can be used to set a few registers during boot or on shutdown to
control reset handling, which is all we need it for.

The patch adding platform support for sc7180 landed around roughly the
same time as the patch that changed GICV3_IMPL to GICV3_SUPPORT_GIC600.
Thus the sc7180 Makefile is still using the old variable name which now
no longer does anything, and it hangs on boot due to the lacking GIC-600
support. This patch fixes the issue.
