A recently added feature to the firmware enables the driver to retrieve
firmware logs via the host bus (SDIO or SPI).
There are two modes of operation:
1. On-demand: The FW collects its log in an internal ring buffer. This
buffer can later be read, for example, upon recovery.
2. Continuous: The FW pushes the FW logs as special packets in the RX
path.
Reading the internal ring buffer does not involve the FW. Thus, as long
as the HW is not in ELP, it should be possible to read the logs, even if
the FW crashes.
A sysfs binary file named "fwlog" was added to support this feature,
letting a monitor process read the FW messages. The log is transferred
from the FW only when available, so the reading process might block.

This patch adds support for the new wl12xx firmware (Rev 6.1.3.50.49)
Since this fw is not backward compatible with previous fw versions,
a new fw (with different name) is being fetched.
(the patch is big because it contains all the required fw api changes.
splitting it into multiple patches will result in corrupted intermediate
commits)

All files name prefix removed due to the fact that wl12xx driver supports
wl1271 and wl1273.
Also the definition in Kconfig and header files changed respectively.

wl12xx is a driver for TI wl1251 802.11 chipset designed for embedded
devices, supporting both SDIO and SPI busses. Currently the driver
supports only SPI. Adding support 1253 (the 5 GHz version) should be
relatively easy. More information here:
