[PATCH v6 0/4] soc: qcom: ubwc: Fix link error when QCOM_SMEM=n

[Daniel Baluta <daniel.baluta@nxp.com>]

DRM_MSM and VIDEO_QCOM_IRIS select QCOM_UBWC_CONFIG, whose
ubwc_config.c calls QCOM_SMEM APIs unconditionally. On configs without
QCOM_SMEM this fails to link, e.g. on SOC_IMX5:

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

Fix it by making the QCOM_SMEM requirement explicit in Kconfig.

Changes since v5:
 * added patch 4/4 to this series, which was initially sent as a
 standalone patch (addresses review from Nathan)
 * no other change to the series.
 * picked up all R-b and Acked-by tags.
