core: enable non-contiguous temporary reference parameters

Now, when we can pass list of pages between REE and TEE it is possible
to use temporary memory references that are not located in a preallocated
shared memory area. By employing OPTEE_MSG_ATTR_NONCONTIG parameter
attribute, REE can provide own buffer as a temporary memory reference.

Actually, such parameters are indistinguishable from registered shared
memory references. So, when OP-TEE spots temporary memory reference with
OPTEE_MSG_ATTR_NONCONTIG attribute, it will create `mobj_reg_shm` for it.
After call was handled, it will free that mobj.

core: add code for the interrupt framework

With this commit, we add three more GIC APIs for the kernel of OPTEE-OS:
itr_raise_sgi : can raise software generate interrupt(SGI) from secure
world to no-secure world, or secure world to secure world. It's a quick
communication between different worlds and different cores. Because SGI
is using the GIC N-N model, so with this API, every core can receive
the interrupt if want.

itr_raise_pi : can trigger the peripheral interrupt with the corresponding
interrupt number. When sending it to N cores, just one core can receive
the effective interrupt.

itr_set_affinity : can target the peripheral interrupt to the core you
want, it means that one can bind the interrupt to the corresponding core
use this API.

The usage may as follow:
itr_raise_sgi(11, 0x1 << 1)
it will raise SGI11 to core 1, and if you want not only core 1 can receive
SGI11 but also core 2, then you can change the code to
itr_raise_sgi(11, 0x1 << 1 || 0x1 << 2).

itr_set_affinity(61, 0x1 << 1)
itr_raise_pi(61)
These two APIs may use together, the operation set_affinity set the PI61
can just sent to core 1, then raise_pi, core 1 will receive the peripheral
interrupt 61.
