Switch from the deprecated of_property_read_bool() to the common device_property_read_bool() API. This makes the driver agnostic to the underlying firmware interface (DT or ACPI) and simplifies the logic.

Since the driver is no longer strictly dependent on Device Tree, include <linux/mod_devicetable.h> directly for the struct of_device_id definition, instead of relying on implicit inclusion via <linux/of_irq.h>, which has been removed as it is unused.

Also rename apb_ctrl_get_devtree_data() to apb_ctrl_get_fw_data() to better reflect the agnostic nature of the new implementation.
