Commit 4afc37 (wlcore: reorder identify_chip and get_hw_info) broke
support for wl127x chips.

When we moved the identify_chip operation to an earlier stage (ie. to
the probe function), we broke wl127x support because during HW init we
would set the WLCORE_QUIRK_TX_BLOCKSIZE_ALIGN.

To avoid this, set this quirk in the identify_chip operations and only
force it to be unset if the bus module doesn't support it.  We were
doing the opposite and setting the flag if the bus module supports it.

The number of RX packet descriptors may vary from chip to chip and
in different firmware versions.  Unfortunately, the array that
contains the actual descriptors is in the middle of the fw_status

calculate the offset of what comes after the array and access the last
elements more easily.

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).
