Subject: [PATCH v3] 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.

Acked-by: Mark Brown <broonie@...nel.org>

BRANCH: mtd/next

Changes in v3:
 - Updates to 'resets' and 'reset-names' removed for non-Versal platforms.
 - Updated patch description.
 - Added Mark's Acked-by tag.

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