soc: qcom: ubwc: Fix link error when QCOM_SMEM=n

ubwc_config.c calls qcom_smem_is_available() and qcom_smem_dram_get_hbb()
unconditionally, so QCOM_UBWC_CONFIG=y with QCOM_SMEM=n fails to link:

  arm-linux-gnueabihf-ld: ubwc_config.c:(.text+0x2c): undefined
      reference to 'qcom_smem_is_available'

Add the missing 'depends on QCOM_SMEM'.
