Function: LED_Init
Parameters
banks: an unsigned char with a 1 in each position to set the bank as an LED
bank, should be a bitwise OR of the #define'd LED_BANKx values.
Returns
char: SUCCESS or ERROR
Description
Initializes the LED subsystem, sets each pin in the bank as a digital output
and turns the LED on.
Notes: J3 SPI Jumpers should be set in MASTER position.
