This patch series adds support for the Qualcomm RPMH power domain
driver, responsible for managing power domains on Qualcomm SoCs.
The driver is ported from the Linux kernel and adapted for
U-Boot to enable proper power domain control on SA8775P platform.

Changes in v2:
- Added ARCH_SNAPDRAGON dependency to QCOM_POWER_DOMAIN in drivers/power/domain/Kconfig 
- In drivers/power/domain/qcom-rpmhpd.c, the un-supported power domains are handled with warning
- Power domain fixups have been removed since they are now managed by drivers/power/domain/qcom-rpmhpd.c
- Link to v1: https://lore.kernel.org/u-boot/20250626112441.143064-1-aswin.murugan@oss.qualcomm.com/
