Subject[PATCH 2/2] rtlwifi: rtl8192de: make arrays static const, makes object smaller

From: Colin Ian King <colin.king@canonical.com>

Don't populate arrays the stack but instead make them static const
Makes the object code smaller by 852 bytes.

text data bss dec hex filename
128211 44250 1024 173485 2a5ad ../realtek/rtlwifi/rtl8192de/phy.o

After:
text data bss dec hex filename
127199 44410 1024 172633 2a259 ../realtek/rtlwifi/rtl8192de/phy.o

(gcc version 10.2.0)
