process_isr? That isn't a good name for something...

This commit adds UART timer based functionality to the FX2. The same steps are applicable to this pull request to make and build use the following steps:
To run this first clone the repository, then cd to the fx2lib directory and checkout this particular branch.
After this run 2 commands:
git submodule initgit submodule updatemakeAfter this , navigate to the examples/uart_timer directory and execute the following commands:
makeNow push the FX2 device inside the USB port(remove any udev rules you may have set up for Cypresse's VID and PID) and run
make fx2_downloadAfter this open minicom
sudo minicom -H -w name_of_configurationYou should see the data which is read from the EEPROM displayed on your console. Make sure the UART0 pins are connected to the appropriate GPIO's on the FX2. Currently the speed supported is 9600bps. Make sure this is set correctly. Currently the pins are hardwired, however after the fast_uart is merged this will be updated, and we will use macros to create this automatically. Currently TX is PA4, RX is PA5 on the FX2.
