core: rename secure_partition to stmm_sp

The current secure partition code is used for the stmm SP. Rename it so
we can start integrating the FF-A secure partitions.

Backwards compatibility is maintained when CFG_STMM_PATH is used to
enable support for STMM. The internal configuration flag
CFG_WITH_SECURE_PARTITION is renamed to CFG_WITH_STMM_SP.

core: remove struct tee_ta_ctx from struct user_mode_ctx

Removes struct tee_ta_ctx from struct user_mode_ctx allowing a user mode
entity to be independent of the TA concept, that is, making room for SPs
in user mode.

A pointer to a struct user_mode_ctx is passed to many memory management
functions where a pointer to a struct ts_ctx is needed too. Prior to
this patch it was possible to calculate that address of corresponding
struct ts_ctx with help of the container_of() macro, that is no longer
possible. Instead is a struct ts_ctx *ts_ctx field added to struct
user_mode_ctx in order to allow such lookups.

core: add generic struct ts_session

As a step in making room for Secure Partitions (SPs) running at S-EL0
add a Trusted Service (TS) abstraction. Both TAs and SPs is a TS.

Adds the generic struct ts_session. All future sessions structs
(currently only struct tee_ta_session exists) should add this struct to
allow generic session operations.

With this struct comes new functions replacing previous struct
tee_ta_session oriented functions. The following functions are replaced
as:
tee_ta_get_current_session() -> ts_get_current_session()
tee_ta_push_current_session() -> ts_push_current_session()
tee_ta_pop_current_session() -> ts_pop_current_session()
tee_ta_get_calling_session() -> ts_get_calling_session()

ts_get_current_session() is changed compared to its predecessor to
panic() in case of failure to return a valid pointer.

A new function ts_get_current_session_may_fail() is added to handle an
eventual case where a return NULL session may be handled.

core: refactor locking during user TA load

tee_ta_init_user_ta_session() unlocks tee_ta_mutex while loading ldelf
and the user TA. This avoids a window where deadlock can occur in case
pgt_alloc() goes to sleep.

A new condition variable, tee_ta_init_cv, is added to signal that a TA
has changed state while initializing.

tee_ta_init_session_with_context waits for a TA context be fully
initialized before assigning it to another session.

This also simplifies tee_ta_try_set_busy() since it now doesn't have to
handle the case where it has to wait for a TA context to be fully
initialized.
