lib: utils/irqchip: Avoid redundant writes to APLIC CLRIE register
Each APLIC CLRIE register allows disabling 32 interrupt sources at
a time by writing -1 so no need to write CLRIE register separately
for each interrupt source.
Fixes: 99792653de29 ("lib: utils/irqchip: Add APLIC initialization library")
