[oe] [meta-oe][PATCH] cpuburn-arm: add aarch64 machine and build configuration

[Andrey Zhizhikin]

Add aarch64 as a valid machine to cpuburn recipe and split compilation
task.

The only source file which supports the aarch64 build is cpuburn-a53.S,
and in case if TUNE is set to aarch64 - this should be the only file to
be assembled to the application.

In case of 32-bit build - all sources are compiled as they are, since
cpuburn-a53.S supports both 32- and 64-bit tunes.
