G/C gtmr_init function declaration

gtmr: Add support for arm,cpu-registers-not-fw-configured property.

On armv7, arm,cpu-registers-not-fw-configured means that firmware hasn't
bothered to configure any generic timer registers and we need to
initialize cntfrq ourselves.

Revert "Include opt_diagnostic.h for DIAGNOSTIC."

This did not do what I thought it did. opt_diagnostic.h is only for
the unused _DIAGNOSTIC, which seems like an abortive attempt to
incrementally convert DIAGNOSTIC to an opt_*.h option rather than a
command-line option.

Include opt_diagnostic.h for DIAGNOSTIC.

...at least, in header files, which may not have already included
libkern.h.

Add support for physical timers and sprinkle isb where needed.

Revert gtmr.c r1.27 and apply a workaround for Allwinner A64 SoCs based
on analysis of the issue from LKML: https://lkml.org/lkml/2018/5/10/774

Since this bug is specific to the Allwinner A64 SoC, only apply the
workaround when the root ("/") node of the device tree is compatible
with "allwinner,sun50i-a64".

Remove unused gtmr_bootdelay.

branches: 1.9.2;
When attaching gtmr at fdt use fdtbus_intr_establish to establish the
gtmr interrupt.

Add __HAVE_GENERIC_CPU_INITCLOCKS option. If set, don't export
cpu_initclocks from device drivers as common code (in this case FDT) will
provide its own copy.
