nvadsp: AMC and AMISC changes for multi-instance

- With multiple ADSPs in use, only one of them may configure AMC,
    so use amc_not_avlbl flag to skip reg parsing, if not needed
 - Unify reg enums for ADSP and AON; this means that reg DT prop
    for AON should have a dummy first entry (against AMC)
 - Remove adsp_prid from chip data, as AMISC base in reg DT prop
    will be offset as per the ADSP instance
