Adapt to latest changes to IPA micro-controller (IPA uC).
For pipe SUSPEND, IPA uC will fail in case the pipe is not empty.
IPA driver needs to insure pipe is empty and then issue a SUSPEND command.
For pipe DISABLE, pipe is already empty on SUSPEND,
IPA driver does not need to do ensure anything before
issuing a DISABLE command.

IPA and GSI firmwares are saved on the file-system as an
ELF file. IPA driver extracts the firmwares and load
them during driver initialization.
This change adds validation steps to each firmware before
loading: load addresses, memory sizes, firmware sizes and
more...

commit 5a00b6c2438460b870a451f14593fc40d3c7edf6 upstream.
The commit 1c6c69525b ("genirq: Reject bogus threaded irq requests")
starts refusing misconfigured interrupt handlers. This makes
intel_mid_powerbtn not working anymore.
Add a mandatory flag to a threaded IRQ request in the driver.

with a high bandwidth requirement, enable the big CPU cluster
and adjust the affinity of the wil6210 interrupt to run on
the first big core. The first big core is selected because
WLAN driver uses the other cores.

Also make a change to read all the rx_ch_stats to avoid

Following this bug report[1], there are other cases like this one, but
