With commit f4e871509959 ("clk: iproc: Make clocks visible options"),
COMMON_CLK_IPROC gained a dependency on ARCH_BCM_IPROC, yet CLK_BCM_63XX
also selects that option, this causes the following Kconfig warning:
warning: (CLK_BCM_63XX) selects COMMON_CLK_IPROC which has unmet direct
dependencies ((ARCH_BCM_IPROC || COMPILE_TEST) && COMMON_CLK)
Fix this by adding proper depends/default for COMMON_CLK_IPROC
Fixes: f4e871509959 ("clk: iproc: Make clocks visible options")

It's confusing that CLK_BCM_63XX selects COMMON_CLK_IPROC and the
other drivers don't. Also, why are we now defaulting IPROC to be
true when ARCH_BCM_63XX is there? It will be selected anyway by
the clk driver on that machine so what's the point?
I'd prefer we handled this one way instead of two. Given that
COMMON_CLK_IPROC is a symbol for what looks like a library it
seems that it needs to be a hidden option that gets selected by
the other three options for the machine specific drivers.
I'd like to drop the default ARCH_BCM_63XX part of your patch,
merge that for 4.9 and apply this on top for 4.10. Agreed?

So essentially you propose to revert the change that you suggested Jon
to do in the Fixes commit mentioned, that's fine with me.

Not exactly. We always wanted to have the option of compiling
support for different drivers from the menu, which is what Jon's
change was about. The difference here is that we don't require
the support library code to be selected to make those options
visible.
Anyway, it sounds like your fine with this approach so let's do
it! I'll send this patch out properly.
