[PATCH 04/19] vdso/datapage: Define for vdso_data to make rework of vdso possible

[Thomas Weißschuh]

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

PTP clocks could also be supported by the vdso to use the advantages of
this implementation. Therefore the struct must be reworked. For a
transition to the new structure of the vdso, add a define which maps
vdso_clock to vdso_data. This will be removed when all users are updated
step by step.

No functional change.
