Add patch fixing rmmod and insmod. Lots of flawed logic fixed that
permits the module to correctly rmmod and insmod later.
Just to quote some change, use phy_detach instead of phy_disconnect, fix
exclusive reset_control that could only be used once, fix kernel panic
on second edma_cleanup, stop traffic before module exit...

Since 6.5 netdev_rx_queue was moved out of netdevice.h so include the new
header since that is where it lives now.

Might be a typo in drv->txtstamp function:
+ phy_rxtstamp(ndev->phydev, skb, 0);
to
+ phy_txtstamp(ndev->phydev, skb, 0);

In the recent NSS-DP update FDB roaming fix we had was removed as in
testing no issue were reported, but after it was merged the old duplicate
MAC issue reappeared so lets port the previous FDB fix to work with newer
NSS-DP.
Fixes: 4ee444b5da ("kernel: qca-nss-dp: update to 12.4.5.r1")

Qualcomm has finally started the preparatory work in order to support
kernel 6.1, so lets make use of that and update NSS-DP 12.4.5.r1 which
allows us to drop almost some of the patches.

Currently kernel crashes when of_phy_connect has issues:
Unable to handle kernel access to user memory outside uaccess routines at virtual address 0000000000000308
...
pc : phy_attached_print+0x28/0x1b0
lr : phy_attached_info+0x14/0x20
...
Call trace:
phy_attached_print+0x28/0x1b0
phy_attached_info+0x14/0x20
nss_dp_adjust_link+0x544/0x6c4 [qca_nss_dp]
of_phy_connect returns either pointer or NULL, so can't be checked with
IS_ERR macro.

Qualcomm NSS-DP is as its name says Qualcomms ethernet driver for the NSS
subsystem (Networking subsystem) built-into various Qualcomm SoCs.
It has 2 modes of operation:
* Without NSS FW and rest of code required for offloading
This is the one that we will use as the amount of kernel patching required
for NSS offloading and the fact that its not upstreamable at all makes it
unusable for us.
Driver in this mode is rather basic, it currently only offers NAPI GRO
(Added by us as part of the fixup) and basically relies on the powerfull
CPU to get good throughput.
* With NSS FW and rest of code required for offloading
In this mode, driver just registers the interfaces and hooks them into
NSS-ECM to allow offloading.
This mode is not viable for use in OpenWrt due to reasons already described
above.
This driver is required for ipq807x to have wired networking until a better
one is available, so lets add the fixed-up version for 5.15 for now.
