spi: bcm-qspi: Fix probe regression on iProc platforms 

iProc chips have QSPI controller that does not have the MSPI_REV
offset. Reading from that offset will cause a bus error. Fix it by
having MSPI_REV query disabled in the generic compatible string.

Fixes: 3a01f04d74 ("spi: bcm-qspi: Handle lack of MSPI_REV offset")
