[PATCH] time: Make VIRT_CPU_ACCOUNTING_GEN depend on GENERIC_CLOCKEVENTS

[Arnd Bergmann]

Moving the CONTEXT_TRACKING Kconfig option into kernel/time/Kconfig
added an implicit dependency on the surrounding GENERIC_CLOCKEVENTS
option, but this is not always enabled when we are able to select
VIRT_CPU_ACCOUNTING_GEN:

WARNING: unmet direct dependencies detected for CONTEXT_TRACKING
  Depends on [n]: GENERIC_CLOCKEVENTS [=n]
  Selected by [y]:
  - VIRT_CPU_ACCOUNTING_GEN [=y] && <choice> && HAVE_CONTEXT_TRACKING [=y] && HAVE_VIRT_CPU_ACCOUNTING_GEN [=y]

Platforms without GENERIC_CLOCKEVENTS are rare enough that we can
probably just ignore that corner case and make it a dependency for
VIRT_CPU_ACCOUNTING_GEN to simplify the configuration.
