bl32: add secure interrupt handling in AArch32 sp_min
Add support for a minimal secure interrupt service in sp_min for the AArch32 implementation. Hard code that only FIQs are handled. Introduce bolean build directive SP_MIN_WITH_SECURE_FIQ to enable FIQ handling from SP_MIN. Configure SCR[FIQ] and SCR[FW] from generic code for both cold and warm boots to handle FIQ in secure state from monitor. Since SP_MIN architecture, FIQ are always trapped when system executes in non secure state. Hence discard relay of the secure/non-secure state in the FIQ handler.
