[PATCH wireless-next v3 2/4] wifi: mac80211: update ML STA with EML capabilities

[Rameshkumar Sundaram <quic_ramess@xxxxxxxxxxx>]

From: Ramasamy Kaliappan <quic_rkaliapp@xxxxxxxxxxx>

When an AP and Non-AP MLD operates in EMLSR mode, EML capabilities
advertised during Association contains information such as EMLSR
transition delay, padding delay and transition timeout values.

Save the EML capabilities information that is received during station
addition and capabilities update in ieee80211_sta so that drivers can use
it for triggering EMLSR operation.
