Subject: ACPI: power: Use acpi_handle_debug() to print debug messages
Patch-mainline: v5.15-rc1
Git-commit: fad40a624854ad14a88ee0277b9e8207bfc6d95a
References: jsc#SLE-19223

Use acpi_handle_debug() to print diagnostic messages regarding ACPI
power resources so as to make it easier to correlate the kernel
messages with the power resource objects in the ACPI namespace that
they are about.
