watchdog: Don't discard irqprio data due to CONFIG_LTO
Don't discard irqprio data when the IRQ_PRIORITY macro is used directly
(for watchdog / watchdog timer).
This change is probably a NOP for all platforms, since the power-on
default for the IRQ prio register seems to be zero, which is the same
priority we're setting in our direct use of IRQ_PRIORITY.
BUG=chromium:634701
BRANCH=None
TEST=Verify 'prio_44' entry exists in irqprio section by checking
ec.RO.map on kevin.
