lib: utils/irqchip: Automatically delegate T-HEAD PLIC accessOpenSBI-v0.9-78c2b19
The T-HEAD PLIC implementation requires setting a delegation bit
to allow access from S-mode. Now that the T-HEAD PLIC has its own
compatible string, set this bit automatically from the PLIC driver,
instead of reaching into the PLIC's MMIO space from another driver.
