Add find5 support to arch/arm/mach-msm

Done by copying board-8064-*.c and manually applying oppo
changes (ref: Sony fusion3 boardfile organization)

Oppo's changes to acpuclock-8064 were not pulled in as
the changes were an upstream cherry-pick from CAF that
is present already in jb_2.5

Also intentionally left out are the acpuclock-krait sysfs changes

Changes to common files were ifdefed with CONFIG_MACH_OPPO_FIND5,
which will replace CONFIG_VENDOR_EDIT as we clean things up.
