Looks like the person, who add sst26wf* flash series support to Linux
only use/test reading from these flash ICs and reading works fine
as only write protection implementation was changed.

Also it ids possible that these write protection bits were cleared
by prebootloader on platform there that patch was test - so flash
IC was already unlocked.

BTW: I have plans to port this patch to linux too.
