arm64: dts: qcom: msm8996: Define UFS UniPro clock limits
[ Upstream commit 68c4c20848d71b0e69c3403becb5dd23e89e5896 ]
These limits were always defined as 0, but that didn't cause any issue
since the driver had hardcoded limits. In commit b4e13e1ae95e ("scsi: ufs:
qcom: Add multiple frequency support for MAX_CORE_CLK_1US_CYCLES") the
hardcoded limits were removed and the driver started reading them from DT,
causing UFS to stop working on MSM8996. Add real UniPro clock limits to fix
UFS.
