ACPI: processor: idle: Set pr->flags.power unconditionally

ACPI: processor: idle: Set pr->flags.power unconditionally

acpi_processor_get_power_info_default() ensures that the processor's
ACPI_STATE_C1 state is always valid. Consequently, the pr->flags.power
should be set unconditionally after this.

Remove conditional checks and directly set pr->flags.power.

No functional change.
