Reserve a 1.5MiB region of memory to record kmsg dumps, console and
userspace message state into 16kiB ring-buffer slots. The sizing allows
for up to 16 dumps to be captured and read out.
Set max-reason to KMSG_DUMP_EMERG to capture bad-path reboots.

The mismatch lead to a miscalculation of regions in another patch, and
shouldn't be mismatched anyway, so make them consistent.

Enable the second EHCI controller on the AST2600. Also add a line-name
for the GPIO that controls power to the USB port.
The power control is in place to allow the port to be disabled, for
those that are worried about rogue USB sticks.

GPIO Q7 is no longer used for air/water. It is repurposed on Tacoma to
indicate internal FSI (low) vs cabled (high).
GPIO B0 controls the muxing of FSI to the cable (low) or internal pins
(high).

Requesting pinmux configuration is done at driver probe time. The LPC IP
is composed of many sub-devices, each with their own driver, and no
driver exists for the entire IP block. Avoid having each sub-device
request the LPC pinmux by just hogging it in the pinctrl node.
