First patches are misc fixes.

Then there are core enhancements to support ODTR chips.

Last set of patches is Winbond specific, where I add the bulk of the
changes for supporting the new Winbond Octal-DTR SPI NOR chips in the
winbond manufacturer driver, and then sparkle the ID table with the new
IDs and their respective testing logs.
