UAPI: Rearrange definition of HZ in asm-generic/param.h
Rearrange the definition of HZ in asm-generic/param.h so that the user-specific
is declared before the kernel-specific one. We then explicitly #undef the
userspace HZ value and replace it with the kernel HZ value.
This allows the userspace params to be excised into a separate header as part
of the UAPI header split.
