Use acpi_evaluation_failure_warn() introduced previously instead of
the ACPICA-specific ACPI_EXCEPTION() macro to log warning messages
regarding ACPI object evaluation failures and use dev_err() instead
of ACPI_EXCEPTION() to log _PMC package parsing failures, which is
consistent with the other messages printed by the code in question.

Next, drop the ACPI_MODULE_NAME() definition only used by the ACPICA
message printing macro.
