The wowlan support is (partially) determined dynamic by checking the
device/firmware capabilities. So they can differ per device. So it
is not possible to use a static global. Instead use the global as a
template and use kmemdup(). When kmemdup() fails the template is used
unmodified.

On Rt3352 the driver needs to know the frequency of an external
crystal which can be either 40 MHz (as on all other WiSoCs until now)
or 20 MHz.
Get the clock attached by ramips WiSoC platform code which probes
SYSC_REG_SYSCFG (added by John Crispin in commit 6ac8579b96e3b) and
introduce a new flag clk_is_20mhz in struct hw_mode_spec to make the
driver aware and use either 40 MHz or 20 MHz specific rf_vals on those
WiSoC platforms.
The introduced support for boards with a 20 MHz crystal is also needed
for RT5350.

There's no reason to be validating the memory dump types, or
checking them for duplication, or anything, since we really
just pass them through from the TLV to the dump.
Thus, change the way we handle memory dump TLVs to let the
driver just blindly use anything specified there, dumping it
into the memory dump output file.
This makes the system extensible without driver changes.

These drivers use a set of complicated macros to extract and insert
information for the RX and TX descriptors. Driver rtl8192cu had a
different set than was used for the PCI-based drivers. To simplify
the code, rtl8192cu is switched to use the common version. In the
process, two errors in those common macros were found and fixed.
Besides simplifying the code, there is an additional benefit. We have
no BE hardware to test the PCI driver, but using the common macros
provides an additional test for the validity of many endian-sensitive
operations.

The firmware is read from disk as a little-endian byte string. The code
that loads the firmware into the device transfers it as 4-byte quantities.
The routines that write multi-byte quantities on BE hardware assume that
the data are in CPU order, and automatically do the conversion to the LE
order required by the device. As a result, the firmware is transmitted
incorrectly. Rather than do multiple byte swaps on the data, the download
routine is revised to transmit bytes rather than dwords. Although the
number of I/O operations is increased, the firmware is not often loaded.
All drivers have the same bug, and use essentially the same code to
download firmware. These routines have been moved into rtlwifi.
Some CamelCase variables have been renamed.

The debugging macros contain a parameter COMP_XX that could be used as a
mask; however, the code turns all these various bits on at the same time.
This change implements them as a proper mask, and adds module parameters
to set the mask at load time.
The current name "debug" for the debug level has been changed to
"debug_level" to better differentiate it from "debug_mask".
The debug routines have also been changed to interrogate the structure
that is loaded at entry time. As a result, the structure rtl_debug is no
longer needed, and all references to it are deleted.
