Andrejs Cainikovs cf77093e31 arm64: dts: verdin-imx8mm: add ctrl_sleep_moci# hog
Drive CTRL_SLEEP_MOCI# high at boot (SPL) using a GPIO hog, this signal
may be used to control some power-rails on the carrier board, therefore
it should be set to high when the module is booting.

To do this as early as possible is generally a good idea and the issue
was noticed on the Yavia carrier board where it is needed to power the
I2C EEPROM on the carrier board.
