Rename the secure and non-secure interrupts

Currently, the secure interrupts are named as FIQ and the non-secure
interrupts are named as IRQ.

In GICv3 mode, the FIQ and IRQ have different definitions.
* Secure Group 0 interrupts:
Handled by EL3 and triggered by FIQ when running at Secure EL0/1.
* Secure Group 1 interrupts:
Handled by optee_os and triggered by IRQ when running at Secure EL0/1.
* Non-secure Group1 interrupts:
Handled by the rich os and triggered by FIQ when running at Secure
EL0/1.

The "Secure Group 1" interrupts are the "native" interrupts handled by
optee_os. They are same as the "secure" interrupts used in optee_os
for now. But they are triggered by FIQ in GICv2 mode while by IRQ in
GICv3 mode.

The "Secure Group 0" and "Non-secure Group1" interrupts are the
"foreign" interrupts that will cause the exiting of optee_os. (e.g.
switch back to normal world) The "Non-secure Group1" interrupts are
same as the "non-secure"interrupts used in optee_os for now. But they
are triggered by IRQ in GICv2 mode while by FIQ in GICv3 mode.

This patch renames these interrupts to the generic names - "Foreign
interrupts" and "Native interrupts".
For the support of GICv3 mode in the future, we can redefine the macros
of "native interrupt" and "foreign interrupt" to IRQ and FIQ.
