The chip version constant (0xCC33) was taken from version 0001.0105.2011
of the GPL vendor driver. Note that this driver version also ships a
firmware update, but I am unsure if it is required for E-CUT chips to
function properly.
A nearby spelling error was also corrected.

The previous definitions included both {B,C,D,E}_CUT_VERSION and
CHIP_92D_{C,D}_CUT with conflicting values for the C and D cut versions,
and literal hex values were used in the IS_92D_{C,D,E}_CUT macros. So
we clean all this up and in doing so enable cut-specific code paths for
cuts C and D, which would not have been executed because the
CHIP_92D_{C,D}_CUT constants were wrong and the cut version was thus
recorded incorrectly.

Instead of having two memory configuration sets, one for wl127x and
one for wl128x, we can use only one which should be correctly set by
the lower driver.
The wl12xx driver now uses the wl128x memory config by default but
changes it when if it identifies the wl127x chips.

Inverting the quirk flag to indicate Tx-alignment. This aligns it with
the similar Rx-side quirk.
The call to wl1271_set_block_size() decides whether SDIO block size
alignment can be used or not. In case we're using SPI, we can't use
the block size alignment, so the function returns false. So we set
the quirk when wl1271_set_block_size() returns true and let the wl12xx
lower driver unset the bit for wl127x (since it doesn't support this
quirk).

One chip family employs immediate Tx completion, where knowledge of
completed packets is given as part of the FW status. Another is only
notified of Tx completion via the FW status, and has to read the
completion status of the packets from a different location.
Implement the wl12xx tx completion as a delayed Tx completion.

The only difference in the read_data operations is that some chips
need to prepare the data to be read before reading. So instead of
having a mandatory read_data operation, we now have an option
prepare_data operation that only needs to be implemented for chips
that require it.
In the wl12xx lower driver, we only set the prepare_data operation for
wl127x chips.

An aligned data buffer is such where the Ethernet portion of the packet
starts on a 4-byte boundary. Some chip families support padding the Rx
data buffer to achieve such alignment, others rely on the host to perform
it.

support for HW-padded alignment in the Rx flow.
