Update "ipa_reg.h" so that register definitions support IPA hardware version 4.5, in addition to versions 3.5.1 through v4.2. Most of the register definitions are the same, but in some cases fields are added, changed, or eliminated. Updates for a few IPA v4.5 registers are more complex, and adding those definition will be deferred to separate patches. This patch only updates the register offset and field definitions, and adds informational comments. The only code change avoids accessing the backward compatibility register for IPA version 4.5 in ipa_hardware_config(). Other IPA v4.5-specific code changes will come later.
