mtd: nand: spi: winbond: Perform Power-on-Reset(PoR) flash op in cleanup
Flash settings such as Octal-DTR mode and other register configurations
should be resetted before the flash is removed. This would enable
a clean removal and re-plug for later boot stages.
The soft-reset command doesn't restore the flash into 1S mode, so
add support for executing 66h+99h PoR flash reset when in Octal DTR mode.
