build_kernel_image: Use earlycon for arm and arm64
earlyprintk is not supported on arm64. Switch to earlycon instead.
Unfortunately the scripts pass "arm" even for arm64 kernels, so switch
both to using earlycon.
earlycon without any parameters uses the UART and parameters specified
by the "stdout" property in the "chosen" device node.
BUG=none
TEST=build image for arm platform and check config.txt for earlycon
