Revert "ACPI: processor: Update cpuidle driver check in __acpi_processor_start()"
This reverts commit 0089ce1c056aee547115bdc25c223f8f88c08498 which is
upstream commit 6cfed39c2ce64ac024bbde458a9727105e0b8c66.
This commit is causing a suspend regression on systems such as the Asus
Zephyrus G14 (GA402RJ) with Ryzen 7 6700H: when suspending, the display
turns off but the device fails to fully power down. This is not seen
with v7.0-rc1 which indicates that there are changes missing. Therefore,
revert this change.
