qca_spi: Make driver probing reliable

[ Upstream commit becc6399 ]

The module parameter qcaspi_pluggable controls if QCA7000 signature
should be checked at driver probe (current default) or not. Unfortunately
this could fail in case the chip is temporary in reset, which isn't under
total control by the Linux host. So disable this check per default
in order to avoid unexpected probe failures.
