Marek Vasut c2e0363571 mtd: cqspi: Fix division by zero 
Both dummy.nbytes and dummy.buswidth may be zero. By not checking
the later, it is possible to trigger division by zero and a crash.
This does happen with tiny SPI NOR framework in SPL. Fix this by
adding the check and returning zero dummy bytes in such a case.

Fixes: 38b0852b0e ("spi: cadence-qspi: Add support for octal DTR flashes")
