can't boot multiplatform kernel using linaro_deploy_kernel

[Fathi Boudra]

On the road to multiplatform kernel, several platform don't allow to boot using linaro_deploy_kernel action.

It's due to the device configs using bootm only most of the time.
Some platforms have both bootm/bootz enabled in boot_cmds like beaglebone.

We need more platforms converted to support multiplatform kernel.

In pyboot, it's default to bootm and use bootz if the kernel image starts with 'z':

    boot_cmd='bootm'
    if os.path.basename(kimage)[0] == 'z':
        boot_cmd='bootz'

which is fine when you use kernel image build output as is. Personally, I'll add vmlinuz for distro kernel support as well.

Will be included in the 2014.03 release this week.

Note all hwpack / prebuilt (deploy_linaro_image) images will still use bootm.
