soc: qcom: ubwc: provide no-UBWC configuration
After the commit 45a2974157d2 ("drm/msm: Use the central UBWC config
database") the MDSS driver errors out if UBWC database didn't provide it
with the UBWC configuration. Make UBWC database return zero data for
MSM8916 / APQ8016, MSM8974 / APQ8074, MSM8226 and MSM8939.
Fixes: 1924272b9ce1 ("soc: qcom: Add UBWC config provider")
