====================
net: ipa: add IPA v5.5 support

This series adds IPA support for the Qualcomm SM8550 SoC, which uses
IPA v5.5.

The first patch adds a new compatible string for the SM8550.  The
second cleans up "ipa_reg.h" a bit for consistency.  The third patch
adds definitions and some minor code changes related to IPA v5.5.
The fourth defines IPA register offsets and fields used for IPA
v5.0; most--but not all--register definitions are the same as used
in IPA v5.0.  The final patch adds configuration data used for IPA
v5.5 (here again this mostly duplicates IPA v5.0 definitions).
