Bug description:
[Impact]
ACPI error can be found in kernel message:
[ 3.717920] ACPI Error: No handler for Region [SYSI] (00000000ab9e62c5)
[IPMI] (20230628/evregion-130)
[Fix]
On Dell systems that have IPI0001 device, ensure IPMI region is ready
before acpi_power_meter invokes any ACPI method.
[Test]
With the patch applied, no such error can be found in kernel message.
acpi_power_meter sysfs also works correctly.
[Where problems could occur]
If asynchronous probe is disabled, the device drivers that probe after
acpi_power_meter needs to wait until the completion is done, hence the
boot time might be slower.
