The ath79 code uses static clock devices and
provides its own clk_{get,put} implementations.
Change the code to use dynamically allocated
clock devices and register the clocks within
the clkdev framework.
Additionally, remove the local clk_{get,put}
implementation. The clkdev framework has a
common implementation of those.
Also move the call of ath79_clock_init() from
plat_mem_init() to plat_time_init(). Otherwise
it would not be possible to use memory allocation
functions from ath79clock_init() becasuse the
memory subsystem is not yet initialized when
plat_mem_init() runs.

The NR_CPUS_DEFAULT_1 introduced as an aid for the QEMU
platform in 72ede9b189
"[MIPS] Qemu: Fix Symmetric Uniprocessor support"
which was later removed in
302922e5f6
"[MIPS] Qemu: Remove platform."
On certain randconfigs it may happen for NR_CPUS to have an
empty value because not all SMP platforms select a suitable
NR_CPUS_DEFAULT_* value. We fix this by restoring the range
of NR_CPUS to 2..64 and drop the NR_CPUS_DEFAULT_{1,2} symbols.
The first one is no longer used and the latter is not needed since
NR_CPUS=2 is now the default value.
Fixes the following problem on a randconfig:
.config:164:warning: symbol value '' invalid for NR_CPUS

Make KVM_GUEST depend on BROKEN_ON_SMP so that it cannot be enabled with
SMP.
SMP kernels use ll/sc instructions for an atomic section in the tlb fill
handler, with a tlbp instruction contained in the middle. This cannot be
emulated with trap & emulate KVM because the tlbp instruction traps and
the eret to return to the guest code clears the LLbit which makes the sc
instruction always fail.

Several architectures have similar stack debugging config options.
They all pretty much do the same thing, some with slightly
differing help text.
This patch changes the architectures to instead enable a Kconfig
boolean, and then use that boolean in the generic Kconfig.debug
to present the actual menu option. This removes a bunch of
duplication and adds consistency across arches.

The GENERIC_PCI_IOMAP does not depend on CONFIG_PCI so move
it to the CONFIG_MIPS symbol so it's always selected for MIPS.
This fixes the missing pci_iomap declaration for MIPS.
Moreover, the pci_iounmap function was not defined in the
io.h header file if the CONFIG_PCI symbol is not set,
but it should since MIPS is not using CONFIG_GENERIC_IOMAP.
This fixes the following problem on a allyesconfig:
