[RFC PATCH 1/3] mtd: spi-nor: spansion: s25fl256s0: remove SKIP_SFDP flag

[Takahiro.Kuwano at infineon.com]

> That flag was added in [1] to not "issue any non supported commands".
> But since we now have the generic SFDP driver, we'll issue the RDSFDP
> command on most flashes anyway and there was no single complaint. Remove
> the only user of this flag so we can rework the parameter initialization
> in the core.
