A series of updates for the VDSO:

  - Remove the redundant CONFIG_GENERIC_TIME_VSYSCALL after converting the
    remaining users over.

  - Rework and sanitize the MIPS VDSO handling, so it does not handle the
    time related VDSO if there is no VDSO capable clocksource available.
    Also stop mapping VDSO data pages unconditionally even if there is no
    usage possible.

MIPS: VDSO: Fold MIPS_CLOCK_VSYSCALL into MIPS_GENERIC_GETTIMEOFDAY

This configuration option exists so "that we don't provide the symbol
when there's no possibility of there being a usable clocksource".
However it only covers __vdso_gettimeofday() and none of the other vDSO
functions which should be affected by the same circumstances.slightly slightly.

Remove MIPS_CLOCK_VSYSCALL and fold its usecase into
MIPS_GENERIC_GETTIMEOFDAY, which works correctly.
