lib: utils/irqchip: Fix context_map init in irqchip_plic_update_context_map()

Browse Source 
The context_map[][] elements should be initialized with negative
value so that context_map does not point to anything for non-existent
PLIC contexts.

Fixes: 69448a0790 ("lib: utils/irqchip: plic: Provide a hartindex to context map")
