[PATCH 08/12] usb: dwc3: qcom: Inline the qscratch constants

Bjorn Andersson
2023-10-17T03:11:56Z

The two constants for the offset and size of the qscratch block within
the DWC3 region has the same value in all supported variants, so they
don't necessarily need to be picked dynamically.

By replacing the lookup with the constants it's possible to reuse the
same code path without the ACPI pdata structure in the upcoming commit.
