mode_2t2r==1 -> Controls for AB side and CD side are
independent
mode_2t2r==0 -> Controls for channel A are broadcast to all 4
channels.
This control takes effect for both Tx and Rx Enables.
System normally comes up with this bit=1

FDD_MODE
R/W

fdd_mode==1 -> Complete system is in FDD mode. Allows
independent Rx and Fb enables.
fdd_mode==0 -> Atleast one-side (either AB or CD) is in TDD
mode. Allows Rx and Fb chains to be shared and in that case
rxa/b/c/d_fb_shr should be programmed appropriately
System normally comes up with fdd_mode=0
