Jukka Laitinen 3cf28dd0b2 arch/arm64/src/imx9/imx9_lpi2c.c: Fix bus reset 
imx9_lpi2c_reset didn't quite work. It tried to toggle scl line as GPIO, but the line was not even muxed properly.

Instead, set the bus to relaxed mode, and drive address 0 to the bus. This toggles the clock, and also generates start and stop sequences on the bus.

"Relaxed mode" is a new feature on the LPI2C block used in imx93.
