ASoC: SOF: Intel: hda-sdw-bpt: select SND_SOF_SOF_HDA_SDW_BPT properly

When SND_SOC_SOF_INTEL_LNL is set, SND_SOF_SOF_HDA_SDW_BPT must also
be enabled, in order to let the soundwire support call into it.

However, there are configurations with SND_SOF_SOF_HDA_SDW_BPT=m
and SND_SOF_SOF_HDA_SDW_BPT=m but SOUNDWIRE_INTEL=y, which still
lead to a link failure:

aarch64-linux-ld: drivers/soundwire/intel_ace2x.o: in function `intel_ace2x_bpt_wait':
intel_ace2x.c:(.text+0xfc8): undefined reference to `hda_sdw_bpt_wait'
aarch64-linux-ld: drivers/soundwire/intel_ace2x.o: in function `intel_ace2x_bpt_send_async':
intel_ace2x.c:(.text+0x1ff8): undefined reference to `hda_sdw_bpt_get_buf_size_alignment'

Address this by moving the 'select SND_SOF_SOF_HDA_SDW_BPT' into
SND_SOC_SOF_HDA_GENERIC.
