qca_spi: Make driver probing reliable

Browse Source 
[ Upstream commit becc6399ce ]

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.

Fixes: 291ab06ecf ("net: qualcomm: new Ethernet over SPI driver for QCA7000")
