[PATCH 1/7] mmc: msm_sdhci: correct vendor_spec_cap0 register for v5

[Caleb Connolly]

The V4 and V5 controllers have quite varied register layouts. Inherit
the register offsets and naming from the Linux driver. More version
specific offsets can be inherited from Linux as needed.

Fixes: 364c22a ("mmc: msm_sdhci: Add SDCC version 5.0.0 support")
