core: gprof: check that PC sampling is idle before starting

In gprof_start_pc_sampling() check that PC sampling isn't started yet,
or have been stopped before starting again. This avoids memory leakage
by s->sbuf being overwritten with a pointer to a new buffer.

core: Add support to access a TPM event log in secure memory.

Support for OPTEE to be able to receive a TPM event log through
a DTB so it can forward it to a TA (such as a TPM service)
in order to extend the measurements.

CFG_CORE_TPM_EVENT_LOG enables this feature.
CFG_TPM_LOG_BASE_ADDR hardcodes the phys address of the event log
in case CFG_DT is not set.
CFG_TPM_MAX_LOG_SIZE harcodes the size of the event log in case
CFG_DT is not set.

When this feature is enabled, the PTA_SYSTEM_GET_TPM_EVENT_LOG
command is available to any TA.

core: reference count struct mobj

The mobj interface is changed to use reference counting of mobjs, the
direct mobj_free() call is replaced by mobj_put(). As expected a
mobj_get() is also added to handle multiple references to the same mobj.

This also changes already present reference counting in struct
mobj_reg_shm to use the reference counting mechanism now available in
struct mobj.

The VM_FLAG_EXCLUSIVE_MOBJ flag is removed since the referenced mobj is
put instead when a struct vm_region is removed.

- PTAs that implement a GP TEE API (sockets, for example) should be in
core/tee
- PTAs that implement other system services should be in /core/pta
- Test PTAs should be in core/pta/tests
- Platform-specific PTAs belong in the platform's directory
- Architecture-specific (but not platform-specific) PTAs should go
in core/arch/$(ARCH)/pta (there are none currently)
