watchdog: Handle SPL build with watchdog disabled
This patch adds some checks, so that the watchdog can be enabled in main
U-Boot proper but can be disabled in SPL.
This will be used by some AT91SAM based boards, which might enable the
watchdog in the main U-Boot proper and not in SPL. It will be enabled in
SPL by default there, so no need to configure it there. This approach
saves some space in SPL.
