Add i.MX 8M Quad support

- Add CCM driver and clocks implementations for i.MX 8M
- Add GPC driver for iMX8
- Add clock tree for i.MX 8M Quad
- Add clocks support and new compat strings (where required) for existing i.MX 6 UART, I2C, and GPIO drivers
- Enable aarch64-compatible drivers form i.MX 6 in arm64 GENERIC kernel config
- Add dtb/imx8 kernel module with DTBs for Nitrogen8M and iMX8MQ EVK

With this patch both Nitrogen8M and iMX8MQ EVK boot with NFS root up to multiuser login prompt

sys/dev: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Add support for the uart classes to set their default register shift value.
This is needed with the pl011 driver. Before this change it would default
to a shift of 0, however the hardware places the registers at 4-byte
addresses meaning the value should be 2.

This patch fixes this for the pl011 when configured using the fdt. The
other drivers have a default value of 0 to keep this a no-op.

Use the FIFOs in the imx5/imx6 uart hardware instead of interrupting on
each byte sent or received.

Return the actual baud rate programmed in the hardware rather than 115200.
This allows the "3wire" entry in /etc/ttys (with no speed specified) to work.

Reword a comment block a bit; no functional changes.

Flesh out imx_uart_init() so that we're not relying on u-boot to init
the hardware (meaning uarts other than the console will work).

The freescale imx uart driver works for the whole i.MX family, so rename the
header file to not have "5xx" in the name.

Use a more professional device description.

Introduce grab and ungrab upcalls. When the kernel desires to grab the
console, it calls the grab functions. These functions should turn off
the RX interrupts, and any others that interfere. This makes mountroot
prompt work again. If there's more generalized need other than
prompting, many of these routines should be expanded to do those new
things.

Should have been part of r260889, but waasn't due to command line typo.

Fix low-level uart drivers that set their fifo sizes in the softc too late.

uart(4) allocates send and receiver buffers in attach() before it calls
the low-level driver's attach routine. Many low-level drivers set the
fifo sizes in their attach routine, which is too late. Other drivers set
them in the probe() routine, so that they're available when uart(4)
allocates buffers. This fixes the ones that were setting the values too
late by moving the code to probe().
