Subject: [PATCH 02/11] staging: wfx: relocate LINK_ID_NO_ASSOC and MAX_STA_IN_AP_MODE to hif API

From: Jérôme Pouiller <jerome.pouiller@...abs.com>

The definitions LINK_ID_NO_ASSOC and MAX_STA_IN_AP_MODE are imposed by
the hardware. Therefore, they should be located in the hardware
interface API.
