* IS31FL3733 Dirty page fix

Function IS31FL3733_update_led_control_registers was never setting update register to false. As a result the led on/off page was being written every transaction even when it was not modified. This is ineficient and causes lots of bandwidth use.

-> Fix the IS31FL3733_update_led_control_registers.
-> After testing it was evident that failed I2C transactions could corrupt the Led on/off register.
-> Update IS31FL3733_write_pwm_buffer and IS31FL3733_write_register functions to return 0 upon succesful tranmission and 1 if any of the transmitions within the function fail.
-> Modify IS31FL3733_update_pwm_buffers function so if any of the IS31FL3733_write_pwm_buffer transuction fails, the g_led_control_registers_update_required register is set to true forcing a rewrite of the led on/off register in case it was corrupted.
