clocksource: Remove "weak" from clocksource_default_clock() declaration

commit 96a2adbc6f501996418da9f7afe39bf0e4d006a9 upstream.

kernel/time/jiffies.c provides a default clocksource_default_clock()
definition explicitly marked "weak".  arch/s390 provides its own definition
intended to override the default, but the "weak" attribute on the
declaration applied to the s390 definition as well, so the linker chose one
based on link order (see 10629d711ed7 ("PCI: Remove __weak annotation from
pcibios_get_phb_of_node decl")).

Remove the "weak" attribute from the clocksource_default_clock()
declaration so we always prefer a non-weak definition over the weak one,
independent of link order.
