spi: tegra: synchronize PPSB late write
When any write is made to PPSB register, it take time
to actual happen in the register due to ARM-PPSB design.
Delay or readback is required to make sure that write is
completed. There is no worst case guaranteed delay and hence
doing the register read to make write completes actually.
