[net-next] mlxsw: add psample dependency for spectrum

When PSAMPLE is a loadable module, spectrum must not be built-in:

drivers/net/built-in.o: In function `mlxsw_sp_rx_listener_sample_func':
spectrum.c:(.text+0xe357e): undefined reference to `psample_sample_packet'

This adds a Kconfig dependency to enforce usable configurations.

Fixes: 98d0f7b9acda ("mlxsw: spectrum: Add packet sample offloading support")
