4935a885ee timer: Add timestamp_expired() to check for expiry
Rather than open code this each time, create a function for this. The
wrap-around condition may not be needed, if the timer starts at zero,
since we have 64 bits to play with.

TEST=build and boot on daisy

2f7b0116a4 close race condition window in expired timer processing
ensure we cannot miss any timer, no matter how slow is the CPU and how
many simultaneous timer we set.

TEST=boot Link EC and do long key press, see the EC watchdog panic no
longer happening.

1aa57e140e Watchdog fixes
1) When frequency changes, reload the watchdog timer right away, or it
may expire before the next reload.  (Only matters when re-enabling the
PLL.)

2) Split out the timer/task debug output used by the watchdog into
their own routines, instead of assuming it's safe to call the command
handlers.  Also make the flushes in those print routines safe to call
from interrupt level.

470916fb0f Use console output instead of uart output for console commands
This completes console output cleanup.  The remaining calls to
uart_puts() and uart_printf() actually need to be that way.
