Kai-Heng Feng 71113b9be4 hwmon: (acpi_power_meter) Ensure IPMI space handler is ready on Dell systems 
The following error can be observed at boot:
[    3.717920] ACPI Error: No handler for Region [SYSI] (00000000ab9e62c5) [IPMI] (20230628/evregion-130)
[    3.717928] ACPI Error: Region IPMI (ID=7) has no handler (20230628/exfldio-261)

[    3.717936] No Local Variables are initialized for Method [_GHL]

[    3.717938] No Arguments are initialized for method [_GHL]

[    3.717940] ACPI Error: Aborting method \_SB.PMI0._GHL due to previous error (AE_NOT_EXIST) (20230628/psparse-529)
[    3.717949] ACPI Error: Aborting method \_SB.PMI0._PMC due to previous error (AE_NOT_EXIST) (20230628/psparse-529)
[    3.717957] ACPI: \_SB_.PMI0: _PMC evaluation failed: AE_NOT_EXIST

On Dell systems several methods of acpi_power_meter access variables in
IPMI region [0], so wait until IPMI space handler is installed by
acpi_ipmi and also wait until SMI is selected to make the space handler
fully functional.

Since the dependency is inside BIOS's ASL code and it's not
discoverable, so use this fixup is a hack to workaround BIOS issue.
