lib: utils: Allow PLIC functions to be used for multiple PLICs
We extend all PLIC functions to have a "struct plic_data *" parameter pointing to PLIC details. This allows platforms to use these functions for multiple PLIC instances. Signed-off-by: Anup Patel <anup.patel@wdc.com> Reviewed-by: Atish Patra <atish.patra@wdc.com>
