arm64: dts: ti: k3-am62-verdin-dahlia: support sleep-mocitoradex_ti-linux-6.1.y
Previously, we had the sleep-moci pin set to always on. However, the
Dahlia carrier board supports disabling the sleep-moci when the system
is suspended to power down peripherals that support it. This reduces
overall power consumption. This commit adds support for this feature by
disabling the reg_force_sleep_moci regulator and adding a new regulator
for the USB hub that can be turned off when the system is suspended.
