powerpc/44x/Akebono: Remove select of IBM_EMAC_RGMII_WOL

Commit 2a2c74b2efcb ("IBM Akebono: Add the Akebono platform") added a
select of IBM_EMAC_RGMII_WOL. But that Kconfig symbol isn't (yet) part
of the tree. So this select has been a nop since that commit was
included in v3.16-rc1.

powerpc/lib: Do not include string.o in obj-y twice

In the Makefile, string.o (which is generated from string.S) is
included into the list of objects being built unconditionally
(obj-y) in line 12.

Additionally, if CONFIG_PPC64 is set, it is included again in
line 17.

This patch removes the latter unnecessary inclusion.

powerpc/kvm: Create proper names for the kvm_host_state PMU fields

We have two arrays in kvm_host_state that contain register values for
the PMU. Currently we only create an asm-offsets symbol for the base of
the arrays, and do the array offset in the assembly code.

Creating an asm-offsets symbol for each field individually makes the
code much nicer to read, particularly for the MMCRx/SIxR/SDAR fields, and
might have helped us notice the recent double restore bug we had in this
code.
