[PATCH] ACPI: processor: idle: expose max_cstate/nocst/bm_check_disable read-only in sysfs

[Yajun Deng <yajun.deng@linux.dev>]

This patch exposes max_cstate/nocst/bm_check_disable in read-only sysfs.
This will allow super users to verify them when changed in grub.

The parameters "nocst/bm_check_disable" is only used to be enable/disable.
So change them from integer to bool.
