[PATCH v3 0/4] powerpc: trivial unused functions cleanup

[Arseny Solokha]

This series removes unused functions from powerpc tree that I've been able
to discover.

Two machines at hands, e300 and e500 based, boot and run without regressions
on my workload with this series applied. The removed code seems also been
rarely touched, so it seems the series is safe at least in general. But I
can't obviously express any strong point in support of the series, so it's
completely OK to leave things as is.

v3: In patch 4/4, do not remove fsl_mpic_primary_get_version() from
    arch/powerpc/sysdev/mpic.c because the patch by Jia Hongtao
    ("powerpc/85xx: workaround for chips with MSI hardware errata") makes
    use of it.

v2: Added a brief explanation to each patch description of why removed
    functions are unused, as suggested by Michael Ellerman.

Arseny Solokha (4):
  powerpc/boot: drop planetcore_set_serial_speed
  kvm/ppc/mpic: drop unused IRQ_testbit
  powrepc/qe: drop unused ucc_slow_poll_transmitter_now
  powerpc/mpic: remove unused functions
