platform-drivers-x86 for v5.4-3

Users of Intel P-Unit IPC driver might be surprised by harmless warning.
Thus, switch to API which doesn't issue a warning at all.

I²C multi-instantiate driver continues to add slave devices even when IRQ
resource is not found. For devices in the market IRQ resource is mandatory,
so, fail the ->probe() of the parent driver to avoid slaves being probed.

Avoid compiler warning due to unused variable in Classmate laptop driver.

The following is an automated git shortlog grouped by driver:

classmate-laptop:
 -  remove unused variable

i2c-multi-instantiate:
 -  Fail the probe if no IRQ provided

intel_punit_ipc:
 -  Avoid error message when retrieving IRQ
