The driver determines the P2P interface address and device
address from the primary mac address. However, the function
used an invalid input. This caused a mac address mismatch
between firmware and driver. This was hidden because the
brcmf_if_add() function corrected the error upon receiving
the IF_ADD event from firmware.

In wl18xx, we use a new ACX command in order to set the remote
supported rates, once we know it (ie. after association).  The wl12xx
firmware doesn't support changing the rates after the STA is started,
so we need to use all supported rates.

Commit 530abe19 (wlcore: add ACX_PEER_CAP command) broke that by using
wlvif->rate_set when starting the STA role.

We can't pass pointers from the platform data to the modules, because
with DT it cannot be done.  Those pointers are not set by the board
files anyway.  It's the bus modules that set them, so they can be
safely removed from the platform data without changing any board
files.

Create a new structure that the bus modules pass to wlcore.  This
structure contains the if_ops pointers and a pointer to the actual
platform data.
