If there is an unhandled KCS/BPC pending interrupt after reboot,
the KCS/BPC Linux driver may trigger interrupts immediately upon
registering the irq. However, since the driver is not yet initialized
to handle them, this can lead to unexpected behavior.
To prevent this, disable KCS/BPC interrupts in u-boot to avoid pending
interrupts from being raised before the Linux driver is fully initialized.

Enabling an eSPI channel(e.g. Peripheral Channel) during
an eSPI transaction might cause the BMC eSPI module to
transition to a wrong state and therefore respond with
FATAL_ERROR on incoming transaction.
Add workaround to avoid the module getting into the wrong
state.

As part of bringing the master branch back in to next, we need to allow
for all of these changes to exist here.

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.
This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.
