This series reworks how the driver determines the HW IP generation and
buttress version, and how it dispatches on them.
Today ivpu_hw_ip_gen() and ivpu_hw_btrs_gen() run a switch over the PCI
device ID on every call, and an unknown ID only triggers a WARN() while
probe continues with an undefined generation. Patch 1 resolves both
values once during device init and fails probe with -EINVAL on an
unrecognized device ID.
With that guarantee in place, patch 2 changes the stored values and their
accessors to the real enum types and drops the default: labels from the
switches that dispatch on them, so -Wswitch flags a generation that is
added later but not handled.
Patch 3 splits the remaining per-generation dispatch in
ivpu_hw_ip_soc_cpu_boot() and pwr_island_delay_set() into helpers that
return directly from each case, removing the locals that were left
uninitialized on the path past the last case.
No functional change is intended beyond failing probe on an unknown PCI
device ID and logging the SOC CPU boot mode even when the boot fails.
