ti_config_fragments: v8_baseport: Enable CPU Idle
Enables CPU Idle framework and the default Menu governor for CPU idle
time management. The framework can be used to customize the CPU idle states
through the sysfs interface [1].
This should not impact existing K3 platforms that do not have idle states
defined in the DT files. Standby WFI state is considered standard on all ARM
platforms [2]. ARM core and cluster level power states other than WFI are
currently unexplored on K3 devices.
There was no noticeable change in power consumption or memory footprint
by enabling this option on AM62x-sk board.
