Subject: [PATCH v2] mtd: spi-nor: add support for sst26wf016b memory IC

This commit adds support for the SST sst26wf016b flash memory IC.
This IC was tested with  "snps,dw-apb-ssi" SPI controller.
We don't test dual/quad reads however sst26wf016b flash's datasheet
advertises both dual and quad reads (and support of corresponding
commands)

Changes v1->v2:
 * drop sst26wf032 support as untested
 * add note about SPI controller used and dual/quad reads to commit
   message.
