cpu/x86/tsc: Deduplicate Makefile logic

The code under `cpu/x86/tsc` is only compiled in when its `Makefile.inc`
is included from platform (CPU/SoC) code and the `UDELAY_TSC` Kconfig
option is enabled.

Include `cpu/x86/tsc/Makefile.inc` once from `cpu/x86/Makefile.inc` and
drop the now-redundant inclusions from platform code. Also, deduplicate
the `UDELAY_TSC` guards.
