Remove the check for zero-length packets as this condition cannot
occur during normal operation. According to the Xilinx AXI4-Stream
FIFO Product Guide (PG080), in the Receive Length Register (RLR)
description: "The smallest packet that can be received is 1 byte."
A zero-length packet would indicate a bug in the IP core itself.

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.
Remove the read_timeout and write_timeout module parameters. The next
commit adds poll() support, allowing applications to implement timeout
handling using standard poll()/select() interfaces.

The packet transmission path in rtw_xmit.c contained TODO comments
indicating a missing lock. This patch implements spin_lock_bh and
spin_unlock_bh around the station attribute update section.
This prevents a potential race condition where station security and
PHY information could be modified on another CPU core during
transmission. The use of _bh variants ensures safety in bottom-half
contexts common in network transmit paths.
Verified that psta is NULL-checked prior to acquisition and that no
double-unlocks occur on the exit path.

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.
