spi: cadence-quadspi: Fix cqspi_setup_flash()

Browse source

commit 858d4d9e0a upstream.

The 'max_cs' stores the largest chip select number. It should only
be updated when the current 'cs' is greater than existing 'max_cs'. So,
fix the condition accordingly.

Also, return failure if there are no flash device declared.
