soc: qcom: ubwc: Add configuration for Hawi

Browse Source 
Add UBWC configuration data for the Hawi platform, which uses UBWC 7.0
and enables the required flags and highest bank bit settings.

This allows drivers to query the correct UBWC capabilities on Hawi.

Also add UBWC 7.0 support to the version tag helper so that
qcom_ubwc_version_tag() returns the correct tag for UBWC 7.0.
