vdso/datapage: Define vdso_clock to prepare for multiple PTP clocks
Multiple PTP clocks, which are independent of timekeeping, are required for
systems, which utilize PTP for synchronizing e.g. automation systems
independent of clock TAI.
PTP clocks are slow to access, but applications require fast access to the
relevant time similar to the regular timekeeping relevant clocks.
To prepare for that the VDSO data representation must be reworked. For
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.
