SPI register for changing mission mode gain in FB.
Uses this value when fbmuxel is indicating msb as '1'
(Meaning no fb is connected) or when
enable_fbmuxel_for_fbdsa is '0'

In FB there is no question of FSPI. The register is kept
together with DSA gain, so that both may be changed together
normally. In case LNA should not take effect,
ext_lna_con_en_fb may be written B"00"
