The cycle counter read is a bit of an expensive operation and requires
locking across all CPUs in a frequency domain. Optimize this by
returning the same value if the delta between two reads is zero i.e
two reads are done in the same sched context for the same CPU.

The find_best_target() selects an active CPU and an idle CPU as
two candidate CPUs. Whichever CPUs saves the most energy compared
to the previous CPU is selected finally. An idle CPU i.e no runnable
tasks but also outside c-state is a good candidate to run the
waking task since the task can run immediately and there is no
idle exit latency. Hence consider such CPU as an active CPU which
helps both power and performance.

Some sub systems operates in 32 bit mode, which could lead
to alignment issues with sub system toc structures.
So update ss toc to use variable instead of pointer.

During insertion of DP adaptor, our target might start in SINK mode
as well. In that case, DP adaptor sends DR_SWAP to change data role
from UFP to DFP. While starting host mode, driver is not clearing
ss_lane_svid variable due to which usb_pd_release_ss_lanes() will
return -EBUSY even though DP client is requesting. Fix the issue by
clearing ss_lane_svid in reset_vdm_state() unconditionally.

When the last rmnet device attached to a real device is removed, the
real device is unregistered from rmnet. As a result, the real device
lookup fails resulting in a warning when the fill_info handler is
called as part of the rmnet device unregistration.
Fix this by returning the rmnet flags as 0 when no real device is
present.
