gpio: aspeed-sgpio: Convert IRQ functions to use llops callbacks

Browse source

Update aspeed_sgpio_irq_handler() and aspeed_sgpio_setup_irqs() to use
the llops callbacks for register access instead of direct iowrite32().
This creates a unified hardware access layer, which is essential for
supporting SoCs with different register layouts like the AST2700.

Additionally, change the loop bounds to use ngpio instead of the static
ARRAY_SIZE(aspeed_sgpio_banks). This allows the driver to adapt to the
actual number of supported pins on the running SoC.
