Merge branch 'qcom-main' of https://gitlab.denx.de/u-boot/custodians/u-boot-snapdragon
* Qualcomm platforms >~2016 gain support for the RPMh (Resource Power Manager)
peripheral which is used to control most regulators. The RB5 is now able to
power up its USB VBUS regulator via the rpmh regulator driver. Git history
from the original Linux driver is preserved for ease of maintenance.
* IPQ40xx SoCs gain ethernet networking support via the new ESS EDMA driver.
