[PATCH] jiffies: Remove unused __jiffy_arch_data

[Petr Pavlu]

The __jiffy_arch_data definition was added in 2017 by commit 60b0a8c3d248
("frv: declare jiffies to be located in the .data section") for the needs
of the frv port. The frv support was removed in 2018 by commit fd8773f9f544
("arch: remove frv port") and no other architecture has required
__jiffy_arch_data. Therefore, remove this unused definition.
