This option was created in commit 554b0004d0ec4 ("vtime: Add
HAVE_VIRT_CPU_ACCOUNTING_GEN Kconfig") for architectures to indicate
they support the 64-bit cputime_t required for VIRT_CPU_ACCOUNTING_GEN.
The cputime_t type has since been removed, so this doesn't have any
meaning. Remove it.

- With VIRT_CPU_ACCOUNTING_GEN, cputime_t becomes 64-bit.
- Before enabling this option, arch code must be audited
- to ensure there are no races in concurrent read/write of
- cputime_t. For example, reading/writing 64-bit cputime_t on
- some 32-bit arches may require multiple accesses, so proper
- locking is needed to protect against concurrent accesses.
