[Buildroot] [PATCH 1/1] configs/spike_riscv64: remove the no longer needed kernel fragment

[Julien Olivain]

Buildroot commit [1] updated riscv-isa-sim (Spike), which now includes
a NS16550 uart emulation. The Kernel config fragment was introduced to
work with older HTIF interface from Spike.

For more information about the HTIF/NS16550 in Spike, see the commit
log [2].

This commit removes this Kernel config fragment, since it is no longer
needed.
