Since commit3bfd7cc(drivers/pc80: Rework normal / fallback selector code) the reboot counter stored in `reboot_bits` isn't reset on a reboot with `boot_option = 1` any more. Hence, with SKIP_MAX_REBOOT_CNT_CLEAR enabled, later stages (e.g. payload, OS) have to clear the counter too, when they want to switch to normal boot. So change the bits to (h)ex instead of (r)eserved. To clarify their meaning, rename `reboot_bits` to `reboot_counter`. Also remove all occurences of the obsolete `last_boot` bit that have sneaked in again since24391321(mainboard: Remove last_boot NVRAM option).
