mtd: spi-nor: Set default Quad Enable method for ISSI flashes

Browse Source 
Set the default Quad Enable method for ISSI flashes. Used for
ISSI flashes (IS25WP256D-JMLE) that do not support SFDP tables
and can not determine the Quad Enable method by parsing BFPT.

Based on code originally written by Wesley Terpstra <wesley@sifive.com>
and/or Palmer Dabbelt <palmer@sifive.com>

- rebase, split and adapt for latest spi-nor/next,
- use PMC CFI ID for ISSI. According to JEP106BA, "Programmable Micro Corp"
  changed its name to Integrated Silicon Solution (ISSI)]
