rtlwifi: rtl8192de: make arrays static const, makes object smaller
[ Upstream commit b05897ca8c821a16ac03850c4704fe460b3f21a0 ]
Don't populate arrays the stack but instead make them static const. Replace
array channel_info with channel_all since it contains the same data as
channel_all. Makes object code smaller by 961 bytes.
