boards/arm/imxrt/imxrt1020-evk: Make naming of the LED consistent. In most places it is referred to as LED1. In board.h it is referred to as USERLED1. The i.MXRT1020-EVK hardware user guide (HUG) uses the name USERLED. This command makes all names internally consistent and consistent with the HUG. Noted by Alin Jerpelea.

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
include/board.h and src/imxrt_autoleds.c. The LED is used to encode
OS-related events as documented in board.h
