paravirt: Remove asm/paravirt_api_clock.h

All architectures supporting CONFIG_PARAVIRT share the same contents
of asm/paravirt_api_clock.h:

  #include <asm/paravirt.h>

So remove all incarnations of asm/paravirt_api_clock.h and remove the
only place where it is included, as there asm/paravirt.h is included
anyway.
