Include console=ttyAMA0 and console=hvc0 in Atomic kickstart
While booting Atomic cloudImage, we want to see kernel messages
on both VGA and serial console. It works fine with
tty1(vga console) and ttyS0(serial console) on x86_64 arch.
But, aarch64 and ppc64le doesn't use ttyS0 as serial console.
Instead, they use ttyAMA0(aarch64) and hvc0 (ppc64le).
Also, good point is that if a serial console specified in kernel
boot parameter is not supported on a given hardware platform, it
gets ignored. For example: console=ttyAMA0 and console=hvc0 will
get ignored on x86_64
