Some APs disconnect clients by sending a Disassociation frame
rather than a Deauthentication frame. Since these frames use
different reason codes in WoWLAN mode, this commit adds support
for handling Disassociation to prevent missed disconnection events.

The preinit is to initialize partial MAC hardware needed before
downloading firmware, and then does post-init after firmware runs.
For RTL8922D, initialize some DMAC and CMAC at this step.

The preload_init is to define preload size from memory to transmitting
buffer. The different generations should call its callback respectively
but suddenly it is missed. However, the register definitions of WiFi 6/7
are the same, things are well. For the coming RTL8922D, settings are
different, so abstract it.

So, change it to be a FW feature group which contains RFK_PRE_NOTIFY_Vx.

The Wi-Fi 7 RF calibration flow has a new design which mainly affect
MLO cases. Before, old RFK H2C command can just send the used channels
and MLO mode even if there are multiple active links. After, each RFK
H2C command should send one channel corresponding to one active link.
For example, connect MLD AP (channel X) and then activate second link
(channel X + channel Y)
Before:
RFK#1: channel X (path A + path B)
RFK#2: channel X (path A) + channel Y (path B)
After:
RFK#1: channel X (path A + path B)
[set MLO mode to focus on 2nd link/channel]
RFK#2: channel Y (path A + path B)
[set MLO mode back to target case]
