core: kernel: dt_driver: fix nodes reference passed in dt_pargs

Correct the DT node references passed in struct dt_pargs. Field
phandle_node is expected to be the node offset of the provider driver
but dt_driver_device_from_node_idx_prop_phandle() implementation passes
node offset -1, dt_driver_device_from_parent() passes the consumer
node offset and dt_driver_device_from_node_idx_prop() may pass the
phandle node offset from a previous index in the parsed DT node property.

Fix that by adding field consumer_node to reference the node offset of
the consumer device and fixing phandle_node where applicable and
update atmel_i2c and stm32_i2c drivers to get the I2C device address
from the consumer_node field instead of the phandle_node that is now
fixed.

core: make generic notifications virtualization-aware

Makes the generic notification handling aware of virtualization. Atomic
events are delivered with a guest_id parameter and asynchronous
notifications are started per guest_id.

struct notif_data is added as guest specific data to be able to track if
notifications are started for a guest.

While this patch compiles it doesn't work as intended without patches
handling the ABI specific side of things.

core: fix race condition on TA/PTA/StMM context loading

Fix race condition on creation of a context for single instance TAs,
PTAs or StMM application. Such race condition could occur and lead to
duplicated contexts if connected close enough that they are created
after tee_ta_init_session() calls tee_ta_init_session_with_context()
and before the context are added in the centralized context list.

This is realized by keeping tee_ta_mutex held while tee_ctxes list is
looked up for matching a context or a new context is added into that
list with its .is_initializing field activated. For that purpose
user TA and StMM application initialization function are split in
2 functions, the 2nd one used to finalizes the context creation
started in the 1st function.

By the way, add inline description comments and fix indentation issues
in uaer_ta.h and remove the inline comment in pseudo_ta.c that refers
to TA loading whereas the function relates to PTA contexts creation.
