wifi: cfg80211: add PD-specific preamble and bandwidth capabilities
Devices may support different preamble and bandwidth configurations
for proximity detection (PD) ranging versus standard ranging. Add
separate pd_preambles and pd_bandwidths fields to
cfg80211_pmsr_capabilities to allow drivers to advertise PD-specific
capabilities.
Expose these over nl80211 using new attributes
NL80211_PMSR_FTM_CAPA_ATTR_PD_PREAMBLES and
NL80211_PMSR_FTM_CAPA_ATTR_PD_BANDWIDTHS, advertised only when
pd_support is set.
For PD requests, validate bandwidth and preamble against pd_bandwidths
and pd_preambles. For non-PD requests, validate against the existing
bandwidths and preambles fields.
