* This patch adds some details on the EL3/Root-Context
and its related interfaces.
* Additionally it updates the existing details on the
interfaces, related to various CPU context entries which
have been improvised recently.

Introduce a new feature state CHECK_ASYMMETRIC to cater for the features
which are asymmetric across cores. This state is useful for platforms
which has architectural asymmetric cores (A feature is only present in
one type of core e.g. big).
This state is similar to FEAT_STATE_CHECK (dynamic detection) except
that feature state is also checked on each core during warmboot path and
override the context (just for asymmetric features) which was setup by
core executing CPU_ON call.
Only Non-secure context will be re-checked as secure and realm context
is created on same core.

This patch adds some documentation for the context management library.
It mainly covers the design at a higher level, with more focus on
the cold boot and warm boot entries as well as the operations
involved during context switch. Further it also includes a section
on feature enablement for individual world contexts.
