gb_lights_light_config() stores channel_count before allocating the
channels array. If kcalloc() fails, gb_lights_release() iterates the
non-zero count and dereferences light->channels, which is NULL.
Allocate channels first and only then publish channels_count so the
cleanup path can't walk a NULL pointer.

Module parameters for timeouts are a poor interface choice as they
affect all device instances globally rather than being configurable
per file descriptor.
The current implementation also returns -EAGAIN on timeout, requiring
userspace to implement retry loops around blocking operations.

commit adds poll() support, allowing applications to implement timeout

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.
