[PATCH 13/19] vdso/namespace: Rename timens_setup_vdso_data() to reflect new vdso_clock struct

[Thomas Weißschuh]

From: Anna-Maria Behnsen <anna-maria at linutronix.de>

To support multiple PTP clocks, the VDSO data structure needs to be
reworked. All clock specific data will end up in struct vdso_clock and in
struct vdso_time_data there will be array of it.

For time namespace, vdso_time_data needs to be set up. But this is only the
clock related part of the vdso_data thats requires this setup. To reflect
the future struct vdso_clock, rename timens_setup_vdso_data() to
timns_setup_vdso_clock_data().

No functional change.
