[PATCH] thermal: broadcom: ns-thermal: depends/default only for NS/NSP

[Jon Mason]

ARCH_BCM_IPROC includes support for many SoCs, not all of which have the
same thermal hardware interface as the Northstar/Northstar Plus SoCs.
This is not a major issue, as this driver will only be probed if the
relevant device tree entry is present.  However, it will result in a
slightly larger than necessary kernel.  By limiting the driver to only
work on the NS/NSP SoCs, we can avoid the issue.

Should this commit message include a Fixes: tag?

Maybe
Fixes: a94cb7e ("thermal: broadcom: add Northstar thermal driver")

Technically, it would be 2 patches

Fixes: a94cb7eeecc4 ("thermal: broadcom: add Northstar thermal driver")
Fixes: a54c51863ed1 ("thermal: broadcom: ns-thermal: default on iProc SoCs")

We could probably get away with only doing the latter one, as it is
the one that makes it enabled by default

Sounds OK, thanks.
