This series adds UFS boot support in SPL for Qualcomm Snapdragon
platforms, along with the necessary driver and infrastructure
changes to support it.

Patch 1 renames SPL_UFS_SUPPORT to SPL_UFS for naming consistency.
Patch 2 adds a Kconfig choice for U-Boot location: sector or partition.
Patch 3 refactors spl_ufs.c to add partition-based U-Boot loading.
Patch 4 adds SPL_UFS_FS Kconfig stub for filesystem-based UFS boot.
Patch 5 enables part_get_info_ptr() in SPL for UFS partition boot.
Patch 6 adds UFS_MODE_RAW and UFS_MODE_FS defines to spl.h.
Patch 7 adds SPL_UFS_QCOM to enable the Qualcomm UFS HC driver in SPL.
Patch 8 adds SPL_PHY_QCOM_QMP_UFS to enable the QMP UFS PHY in SPL.
Patch 9 adds SPL_CLK_STUB Kconfig for the stub clock driver in SPL.
Patch 10 updates charset.o build rule to use SPL_UFS after the rename.
Patch 11 adds SPL_QCOM_GENI Kconfig and $(PHASE_) support for GENI.
Patch 12 adds SPL_PINCTRL_QCOM_* symbols and $(PHASE_) Makefile
support for all Qualcomm pinctrl drivers.
Patch 13 adds SPL_MSM_SERIAL and SPL_MSM_GENI_SERIAL Kconfig and
$(PHASE_) support for Qualcomm serial drivers.
Patch 14 updates Qualcomm PMIC and SPMI Makefiles to use $(PHASE_).
