[Why] Polling SINK_STATUS DPCD can cause some non-DP2.0 LTTPR hubs to hang and no longer respond to AUX. [How] As a workaround for the problem hubs, and also to more closely match DP spec 8b10b behavior, don't poll for intra-hop AUX reply indication on 8b10b-encoded links.

[Why] A hack was used to access DWB register due to difference in the register naming convention which was not compatible with existing SR/SRI* macros. The additional macro needed were added to dwb ip specific header file (dcnxx_dwb.h) instead of soc resource file (dcnxx_resource.c). Due to this pattern, BASE macro had to be redefined in dcnxx_dwb.h, which in turn needed us to undefine them in the resource file. [How] Add a separate macro for DWB access to the resource files that need it instead of defining them in DWB ip header file. This will enable us to reuse the BASE macro defined in the resource file.

One-element arrays are deprecated, and we are replacing them with flexible array members instead. So, replace one-element array with flexible-array member in structs _ATOM_CONNECTOR_DEVICE_TAG_RECORD, _ATOM_OBJECT_GPIO_CNTL_RECORD, _ATOM_BRACKET_LAYOUT_RECORD, _ATOM_BRACKET_LAYOUT_RECORD, _ATOM_LEAKAGE_VOLTAGE_OBJECT_V3, _ATOM_FUSION_SYSTEM_INFO_V3, _ATOM_I2C_DATA_RECORD, _ATOM_I2C_DEVICE_SETUP_INFO, _ATOM_ASIC_MVDD_INFO and refactor the rest of the code accordingly. While at it, removed a redundant casting. Important to mention is that doing a build before/after this patch results in no binary output differences. This helps with the ongoing efforts to tighten the FORTIFY_SOURCE routines on memcpy() and help us make progress towards globally enabling -fstrict-flex-arrays=3 [1].
