[PATCH 2/3] ARM: dts: stm32: drop "st,led1" compatible

[Dario Binacchi]

It is pointless to use the custom compatible "st,led1" when
stm32746g-eval.dts and stm32f769-disco.dts already contain the
"gpio-leds" compatible, which is specifically used for GPIO LEDs
management. In the case of stm32f746-disco.dts, since it lacks the
"gpio-leds" compatible, it was decided to translate "st,led1" into
its "gpio-leds" version in stm32f746-disco-u-boot.dtsi.
