This is to allow for future functionality which may consume
more of the console thread stack.

This resolves sporadic Zephyr crashes on Blackbird hosts
after the host enters skiboot.

This avoids switching to another task and potentially
violating timing / sequencing requirements in the process.

Test case: pressing power button instead of using obmcutil
no longer crashes Zephyr when powering on the host platform.

This fixes LPC clock start failures from the
clock buffer GPIO not being set to output mode.

This avoids a mismatch between BMC internal host state and the
actual physical state of the host if the BMC is rebooted / reloaded
while the host platform is online.

This stabilizes access pending future resolution of place and
route timing failures in the Tercel core on ECP5.

Update build instructions in README

This resolves a BMC crash in late IPL (skiboot / initial kernel load)
exclusively observed on Talos II systems.

Avoid interference between 7 segment display and power LED

This avoids multiple threads interfering with
each other during chassis power operations.

The underlying issue with memory corruption
was fixed in Zephyr PR 35072.

Rework CPU regulator data structures for additional
clarity on configuration.
