The audio controller in the H3 is more or less the same as A10/A20 except
some registers are shuffled around. The mixer interface, however, is
completely different between SoCs. Separate a10_mixer_class and
h3_mixer_class implementations are now made available. This will also make
adding support for other SoCs easier in the future.

* Rename ARM_HAVE_MP_EXTENSIONS to ARM_USE_MP_EXTENSIONS and extend it to
handle more cases, including when SMP is not enabled.
* Check ARM_USE_MP_EXTENSIONS when building for ARMv7+, even if no SMP.
* Use ARM_USE_MP_EXTENSIONS in pmap-v6.c to detect when to set PRRR_NS1.
With this we should be able to boot on all ARMv7+ Cortex-A cores with
32-bit support.

hardware that supports the mp extensions. If so it should use the broadcast
tlb invalidate instructions as other CPUs or devices may need to know about
the invalidation.
To simplify the code have the compiler optimise out the else case when not
builing for Cortex-A8.

This patch adds support for MSI-X interrupts
on Annapurna Alpine platform. MSI-X on Alpine
work similarly to GICv2m, i.e. some range of
SPI interrupts is reserved in GIC and individual
SPIs can be triggered by MSI-X messages.
This SPI range is defined in FDT.

When detaching device trees parent devices must be detached prior to
detaching its children. This is because parent devices can have
pointers to the child devices in their softcs which are not
invalidated by device_delete_child(). This can cause use after free
issues and panic().
Device drivers implementing trees, must ensure its detach function
detaches or deletes all its children before returning.
While at it remove now redundant device_detach() calls before
device_delete_child() and device_delete_children(), mostly in
the USB controller drivers.

- Rename SOC_BCM2837 to SOC_BRCM_BCM2837, put it to opt_soc.h
- do not use files.XXX files, just move required sources to
conf/files.arm64 and make them depend on soc_brcm_bcm2837
