p1022ds: Fix the DIU issue on RevB1 board2009.11-p1022ds-201004291116
DIU doesn't work on P1022DS RevB1 board in u-boot, it is because
there are two code bugs in DIU code.
1) We must clear the PMUXCR[eLBC_DIU] bits before we set the
eLBC_DIU=2'b01 for DIU mode.
The PMUXCR[eLBC_DIU] POR value is 2'b10 in RevB1 board, however
the eLBC_DIU is 2'b00 in RevA board due to design issue.
2) We must do dummy read to make sure the write FPGA PIXIS register
be completed.
