The functions geni_se_select_fifo_mode() and geni_se_select_fifo_mode() are a little funny. They read/write a bunch of memory mapped registers even if they don't change or aren't relevant for the current protocol. Let's make them a little more sane. We'll also add a comment explaining why we don't do some of the operations for UART. NOTE: there is no evidence at all that this makes any performance difference and it fixes no bugs. However, it seems (to me) like it makes the functions a little easier to understand. Decreasing the amount of times we read/write memory mapped registers is also nice, even if we are using "relaxed" variants. Signed-off-by: Douglas Anderson <dianders@xxxxxxxxxxxx>
