soc/intel/baytrail/Kconfig: Remove explicit HAVE_MONOTONIC_TIMER

Fix up commit ce7ecf9c (baytrail: enable monotonic timer), which
selected `HAVE_MONOTONIC_TIMER` explicitly, although it is already
selected by `TSC_MONOTONIC_TIMER` (cf. `src/cpu/x86/Kconfig`).

Therefore remove the explicit selection of that Kconfig option.
