timekeeping: Provide a generic update_vsyscall() implementation
The new generic VDSO library allows to unify the update_vsyscall[_tz]()
implementations.
Provide a generic implementation based on the x86 code and the bindings
which need to be implemented in architecture specific code.
[ tglx: Moved it into kernel/time where it belongs. Removed the pointless
line breaks in the stub functions. Massaged changelog ]
