A single LED is available driven by USR_DEF_RED_LED.
A single LED is available driven GPIO1_IO02. On the schematic this is
USR_DEF_RED_LED signal to pin T1 (GPIO_2). This signal is shared with
KEY_ROW6 (ALT2). A low value illuminates the LED.
This LED is not used by the board port unless CONFIG_ARCH_LEDS is
defined. In that case, the usage by the board port is defined in
