[PATCH v2 07/14] ufs: qcom: add SPL_UFS_QCOM Kconfig and SPL build support

[Balaji Selvanathan]

Add a new SPL_UFS_QCOM Kconfig option to allow the Qualcomm UFS
host controller driver to be built for SPL on Snapdragon platforms.

Switch the ufs-uclass.o and ufs-qcom.o Makefile rules to use the
$(PHASE_) prefix macro so that the correct config symbol
(UFS/SPL_UFS and UFS_QCOM/SPL_UFS_QCOM) is selected automatically
depending on whether SPL or U-Boot proper is being compiled.

Changes in v2:
- Modified the Makefiles rules to use $(PHASE_) prefix instead of
  using SPL_UFS_SUPPORT config
