timestamp: fix incremental linking error for !HAVE_MONOTONIC_TIMER
In linking ramstage a single object file is created before linking
with the linker script. Though there is a weak timestamp_get() symbol
in timestamp.c any of its dependent symbols need to be available
during the incremental link. As not all platforms have
HAVE_MONOTONIC_TIMER enabled this will create a linking error.
Fix this by providing a hint to the compiler to remove dead code
and thus the dependent symbols causing linking errors in the presence
of !HAVE_MONOTONIC_TIMER.
