Luiz Otavio O Souza 801abb3eba Rewrite of ti_i2c based on gonzo's patch, fix the following bugs/problems:
. interrupt storm detected on "intr70:"; throttling interrupt source;

  . Added access serialization on iicbus_transfer(), previously there was
    no such protection and a new transfer could easily confuse the
    controller;

  . Add error checkings (i.e. stop the transfer when a error is detected
    and do _not_ overwrite the previous error);

  . On command done interrupt do not assume that the transfer was finished
    sucessfully as we will receive the command done interrupt even after
    errors;

  . Simplify the FIFO handling;

  . Reset the FIFO between the transfers as the FIFO may contain data from
    the last (failed) transfer;

  . Fix the iicbus speed for AM335x, which in turn will make better use of
    the I2C noise filter (set to one internal clock cycle);

  . Move the read and write handler to ithread instead of notifying the
    requesting thread with wakeup(9);

  . Fix the comments based on OMAP4 TRM.

The above changes allows me to read the EDID from my HDMI monitor on BBB
with gonzo's patches to support TDA19988 (which does 128 bytes reads) and
repeatedly scan the iicbus (with a modified i2c(8)) without lock up the bus.
