From: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

The firmware needs to know the esr_transtition_timeout to time the
transition between EMLSR and single radio with the AP.
Add the EMLSR support bit to the wiphy extended capabilities so that
it'll be sent in our association request frame.
We can set this field unconditionally since it'll be used only if the
MLO is supported.
