IPA register definitions have evolved with each new version. The changes required to support more than 32 endpoints in IPA v5.0 made it best to define a unified mechanism for defining registers and their fields. GSI register definitions, meanwhile, have remained fairly stable. And even as the total number of IPA endpoints goes beyond 32, the number of GSI channels on a given EE that underly endpoints still remains 32 or less. Despite that, GSI v3.0 (which is used with IPA v5.0) extends the number of channels (and events) it supports to be about 256, and as a result, many GSI register definitions must change significantly. To address this, we'll use the same "ipa_reg" mechanism to define the GSI registers. As a first step in generalizing the "ipa_reg" to also support GSI registers, isolate the definitions of the "ipa_reg" and "ipa_regs" structure types (and some supporting macros) into a new header file, and remove the "ipa_" and "IPA_" from symbol names. Separate the IPA register ID validity checking from the generic check that a register ID is in range. Aside from that, this is intended to have no functional effect on the code.
