core: ffa: fix spmc_retrieve_req() buffer

Prior to this patch when retrieving a shared memory block the memory
transaction descriptor (struct ffa_mem_transaction_1_1 or struct
ffa_mem_transaction_1_0) was read from the TX buffer instead of the RX
buffer where the actual memory transaction is supplied. Fix this by
changing to read the memory transaction descriptor from the RX buffer.

This used to work somewhat by chance since OP-TEE before the call to
FFA_MEM_RETRIEVE_REQ_32 filled in a memory transaction descriptor
of what we expect to retrieve in the TX buffer.

core: fix data abort during ftrace

With commit c10e3fa93d24 ("core: fix race in handling TA panic") the
resources of a panicked TAs are released as early as possible, including
the user space mapped ftrace buffer. However, the pointer to the ftrace
buffer is stored in the ts_session for quick and easy access. The ftrace
buffer is always retrieved with get_fbuf() that already have a few other
checks to see if the buffer is currently available. So add a check to
see that the TA hasn't panicked also.

core: riscv: Fix logic of thread_{get/set}_exceptions()

In ARM, the bits in DAIF register are used to mask the interrupts. While
in RISC-V, the bits in CSR XIE are used to enable(unmask) corresponding
interrupt sources.

To not modify the function of thread_get_exceptions(), we invert the
bits after reading the value of CSR XIE, as mask.

To not modify the function of thread_set_exceptions(), we invert the
bits in given "exceptions" before writing "exceptions" into CSR
XIE. Therefore, the intended masked exception bits will be cleared
when we write the final value into CSR XIE to mask those interrupts.

core: riscv: Implement SBI based protocol

Rename thread_return_from_nsec_call() to thread_return_to_ree() for more
general behavior, since TEE might not only be called by REE, but also
do something on its own initiative (e.g., handle secure interrupts).

This commit also implements SBI based protocol used to return control to
REE. The register a7 encodes SBI TEE extension ID, which is temporarily
defined here. We may have ratified SBI TEE extension in the future and
we can apply ratified ID at that time. The register a6 is unused and
encoded as 0. The returned arguments are encoded into registers a0~a5
and should be provided by the caller.
