Subject: [PATCH v7 2/2] mtd: spi-nor: Stop reporting warning message when soft reset is not suported

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

When the software reset command isn't supported, we now stop reporting
the warning message to avoid unnecessary warnings and potential confusion.

v2. only lower the priority for the not supported failure
v3. replace ENOTSUPP with EOPNOTSUPP and check the first command only
v4. move the version information below the '---' line
v5. remove dev_warn if soft reset operation is not supported
