arm64: dts: ti: k3-am62-verdin-dahlia: Keep CTRL_SLEEP_MOCI# regulator on

This reverts commit 3935fbc87ddebea5439f3ab6a78b1e83e976bf88.

CTRL_SLEEP_MOCI# is a signal that is defined for all the SoM
implementing the Verdin family specification, this signal is supposed to
control the power enable in the carrier board when the system is in deep
sleep mode. However this is not possible with Texas Instruments AM62
SoC, IOs output buffer is disabled in deep sleep and IOs are in
tri-state mode.

Given that we cannot properly control this pin, force it to be always
high to minimize potential issues.
