Initial kernel bootup logs get overwritten after running
for a long time, and there can be debugging scenario where
we need initial ~100s bootup logs for debugging.
'android_vh_initial_logbuf' vendor hook is helping in
achieving this purpose.

linux/usb/pd.h has a bunch of timers for which the Type-C spec defines
a range of values. These values have to be tuned based on the latency
observed in a specific architecture. However, linux opensource sets
them to a specific value without providing a mechanism to set board
specific values. While a generic way is figured out, a vendor hook
is needed in the interim.
For instance, tCCDebounce can have a value between 100msec - 200msec.

A vendor hook is added in post_init_entity_util_avg before
a new cfs task's util is attached to cfs_rq's util so that
vendors can gather and modify se's information to modify
scheduling behavior and DVFS as they want.
trace_android_rvh_new_task_stats is not a proper hook because
it is called after the task's util is attached to cfs_rq's util,
which means updating cfs_rq's sched_avg and DVFS request are done.

timerfd doesn't create any wakelocks, but eventpoll can. When it does,
it names them after the underlying file descriptor, and since all
timerfd file descriptors are named "[timerfd]" (which saves memory on
systems like desktops with potentially many timerfd instances), all
wakesources created as a result of using the eventpoll-on-timerfd idiom
are called... "[timerfd]".
However, it becomes impossible to tell which "[timerfd]" wakesource is
affliated with which process and hence troubleshooting is difficult.
Adding vendor hooks to allow vendor to assign appropriate names to
timerfd descriptors and eventoll wakesource.

Like was done for the other non-upstream methods in
'struct ufs_hba_variant_ops', replace ->fill_prdt() with an Android
vendor hook. This is considered to be better because it avoids any
conflicts with upstream changes to 'struct ufs_hba_variant_ops'.
Note that as a side effect of this change, fill_prdt is no longer
allowed to sleep. That's fine for the only known use of this hook.
