Subject: [PATCH v2] mtd: spi-nor: Improve reporting for software reset failures

From: "Chia-Lin Kao (AceLan)" <acelan.kao@...onical.com>

When the software reset command isn't supported, we now report it as an
informational message(dev_info) instead of a warning(dev_warn). 
This adjustment helps avoid unnecessary alarm and confusion regarding
software reset capabilities.

v2. only lower the priority for the not supported failure
