Commit 5f70be08b0 ("Fix autoboot countdown printing wrong") introduces
inconsistency in how the countdown is displayed. For example, in case
when BOOTDELAY=5, the next output is observed during the boot:
Hit any key to stop autoboot: 5
Hit any key to stop autoboot: 4
Hit any key to stop autoboot: 3
That happens due to different printf format (%2d vs %1d). Moreover, the
mentioned commit fails to handle the case when the user is holding some
key before the countdown is shown. E.g. if BOOTDELAY=101, the next
malformed output is being produced:
Hit any key to stop autoboot: 1 0
That's because the fast path code wasn't modified accordingly, and still
tries to erase the number using '\b\b\b' format.
Fix both issues by introducing a dedicated routine for printing the
whole countdown line.
