Subject: [PATCH v3 5/6] gpio: aspeed: Change the macro to support deferred probe

Use module_platform_driver() to replace module_platform_driver_probe().
The former utilizes platform_driver_register(), which allows the driver to
defer probing when it doesn't acquire the necessary resources due to probe
order. In contrast, the latter uses __platform_driver_probe(), which
includes the comment "Note that this is incompatible with deferred
probing." Since our GPIO driver requires access to the clock resource, the
former is more suitable.
