Move options INTRNG into std.armv6 and std.armv7

INTRNG is required on all armv6 and armv7 systems, so make it
standard.

[rpi] Add fdt_pinctrl(4) support to Raspberry Pi GPIO driver

On Raspberry Pi platform GPIO controller also responsible for pins
multiplexing. Pi code predates proper FDT support in FreeBSD so a
lot of pinmux info is hardcoded. This patch:

- Implements pinctl methods in bcm2835_gpio
- Converts all devices with ad-hoc pinmux info to proper pin control
mechanisms and adds pinmux info in FreeBSD's custom dts files.
- Adds fdt_pinctrl option to RPI2 and RPI-B kernels
- Adds SPI pinmux config to FreeBSD's customization of GNU DTS.

Tag all armv7 kernels as such in their machine config line.

Transition all boards that support arm cortex CPUs to armv7. This
leaves two armv6 kernels in the tree. RPI-B, which uses the BCM2835
which has a ARM1176 core, and VERSATILEPB, which is a qemu board setup
around the time RPI-B went in. Copy std.armv6 to std.armv7, even
though that duplicates a lot of stuff. More work needs to be done to
sort out the duplication.

Remove the MULTIDELAY option from arm. It's now enabled when PLATFORM is
enabled.

Remove PLATFORM_SMP. It's unneeded as all configs with both PLATFORM and
SMP use it so we can switch to the combination of these as the check.

Start to deorbit the kernel configs in GENERIC by marking them with
NO_UNIVERSE. This stops them from being built with the universe,
tinderbox, and related targets.

Remove HZ=<various> from all armv6 configs, put HZ=1000 in std.armv6.
All armv6 processors are plenty fast enough for HZ=1000.

No changes are made for older arm systems, because some chips are a bit
wimpy for 1000 while others do fine, so it has to be set on a per-config
basis.

Consolidate debugging options from all arm kernel configs to std.arm[v6].

Rename ARM_INTRNG and MIPS_INTRNG to INTRNG. This will help with machine
independent code that needs to know about INTRNG such as PCI drivers.

Ensure that all arm kernel configs contain ALT_BREAK_TO_DEBUGGER and not
BREAK_TO_DEBUGGER if they have a serial console (most do). A burst of
serial line noise (such as unplugging a usb serial adapter) can look like
a break and drop a working system into the debugger. The alt break sequence
(<CR>~^B) works fine on both serial and non-serial consoles.

Clean up the ARM kernel configs to use 'include<space><tab>"file"'.

Move the first batch of common armv6 options to std.armv6.

Create std.arm and std.armv6 config files and include the right one from
each of the existing kernel configs. This gives a place to put config

Create std.arm and std.armv6 config files and include the right one from
each of the existing kernel configs. This gives a place to put config
that applies to the entire arch.

Add the ARM_NEW_PMAP option to std.armv6. This is working well in early
testing and it's time for wide exposure, but it's still nice to be able
to fall back to the old implementation for testing when a problem comes
along. Eventually the option and the old implementation will go away.

The opportunity now exists to move a whole lot of boilerplate from all the
arm kernel config files into std.arm*, but that's a commit for another day.

Now that DMA works, enable the audio driver on RPi 2.

This is a temporary solution and should be reverted when ARM_NEW_PMAP is

Now that we have an U-Boot for RPI2, do not use the static DTB compiled
into the kernel, which is used mostly on early development stages.

On RPI(2) the DTB is loaded and modified by firmware and then handed to
kernel via U-Boot and ubldr.

The RPI firmware adds (or modify) a few valuable data to the in memory
DTB, like:

- System memory;
- Ethernet MAC address;
- framebuffer settings;
- Board serial and revision;
- clock-frequency for most of devices.

Add support for the Raspberry Pi 2. As the chip is based on the bcm2835 in
the Raspberry Pi B we support most of the devices are already supported,
however the base address has changed.

A few items are not working, or missing. The main ones are:
* DMA doesn't work in the sdhci driver.
* Enabling vchiq halts the boot, may be interrupt related.
* There is no U-Boot port yet so the DTB is embedded in the kernel.

The last point will make it difficult to boot FreeBSD, however there is
support for the Raspberry Pi 2 in the U-Boot git repo. As I have not tested
this it is left as an open task to create a port to build.
