Ido Reis e3b8bbb9e8 wl18xx: FDSP Code RAM Corruption fix
In PG2.0 there is an issue where PHY's FDSP Code RAM sometimes gets
corrupted when exiting from ELP mode. This issue is related to FDSP
Code RAM clock implementation.

PG2.1 introduces a HW fix for this issue that requires the driver to
change the FDSP Code Ram clock settings (mux it to ATGP clock instead
of its own clock).

This workaround uses PHY_FPGA_SPARE_1 register and is relevant to WL8
PG2.1 devices.

The fix is also backward compatible with older PG2.0 devices where the
register PHY_FPGA_SPARE_1 is not used and not connected.

The fix is done in the wl18xx_pre_upload function (must be performed
before uploading the FW code) and includes the following steps:

1. Disable FDSP clock
2. Set ATPG clock toward FDSP Code RAM rather than its own clock.
3. Re-enable FDSP clock
