We have once again reached a point where this board does not build in
some cases with supported toolchains due to reaching a size constraint.
To regain some space, disable support for Plan 9 / RTEMS images with the

This updates the i.MX8MQ device trees and, necessarily, also the
i.MX8MQ clock bindings.  These are taken verbatim from from the
Linux kernel version v5.4-rc2, which three small changes which
were already part of the previous device tree:

 * Keep the PSCI reserved memory range
 * Keep the alias for ethernet, so that the MAC address can be set
 * Keep the modified #include for the IOMUXC pins

The expire_now function was previously setting the watchdog timeout to
minimum and waiting for the watchdog to expire. However, this watchdog
also has bits to trigger immediate reset. Use those instead, like the
Linux imx2_wdt driver does.
Signed-off-by: NRobert Hancock <hancock@sedsystems.ca>

The Linux imx2_wdt driver uses a fsl,ext-reset-output boolean in the
device tree to specify whether the board design should use the external
reset instead of the internal reset. Use this boolean to determine which
mode to use rather than using external reset unconditionally.

For the legacy non-DM mode, the external reset is always used in order
to maintain the previous behavior.

According to IMX28CEC rev. 4, 10/2018, Table 15. Recommended Operating
Conditions, page 16, the VDDD should be set to 1.55V when the CPU is
operating at 454MHz. This is the case in U-Boot, hence increase the
VDDD voltage. This fixes instability when performing TFTP transfers.
Increase the brownout threshold to 1.4V. The documentation recommends
1.45V setting for the brownout, however, this triggers failure during
power block init, so keep the brownout slightly lower.
