Subject: [PATCH v2] spi: dt-bindings: cdns,qspi-nor: Update minItems/maxItems of resets for Cadence OSPI controller

The Cadence Octal SPI (OSPI) controller on AMD Versal SoCs requires only
one reset entry. To reflect this, the maxItems for "resets" and
"reset-names" has been set to 1 for AMD Versal SoCs, and the minItems for
these properties has also been updated to 1.

Signed-off-by: Amit Kumar Mahapatra <amit.kumar-mahapatra@....com>

BRANCH: mtd/next

Changes in v2:
 - Removed "resets" & "reset-names" from required properties.
 - To address review comments, removed "maxItems" from "reset-names".
