fix(fvp): add secure uart interrupt in device region
OP-TEE enables the use case of a secure interrupt triggered by the UART
driver. This interrupt is routed by FFA_INTERRUPT interface to OP-TEE.
Define the UART interrupt in the FF-A device region node.
Without this change, OPTEE panics at the boot with the following:
| I/TC: No non-secure external DT
| I/TC: manifest DT found
| I/TC: OP-TEE version: 4.3.0-23-gfcd8750677db
| I/TC: WARNING: This OP-TEE configuration might be insecure!
| I/TC: WARNING: Please check https://optee.readthedocs.io/en/latest/architecture/porting_guidelines.html
| I/TC: Primary CPU initializing
| E/TC:0 0 assertion '!res' failed at core/drivers/hfic.c:56 <hfic_op_enable>
| E/TC:0 0 Panic at core/kernel/assert.c:28 <_assert_break>
| E/TC:0 0 TEE load address @ 0x6284000
