Remove dead POWER7 code

There are a number of proc_gen branches removed that are trivially
dead code and comments that refer to P7. As well as those:

- Oliver points out that add_xics_icps() must be unused on POWER8
  because it asserts if number of threads > 4, so remove it.

- Change 16b7ae641 ("Remove POWER7 and POWER7+ support") removed all
  references to opal_boot_trampoline, so remove that.

- It also removed the only non-trival choose_bus implementation, so
  that is removed and its caller simplified.

- Remove the paca code, later CPUs use pcia.
