FS#2829 - MikroTik RB951Ui-2HnD has limited functionality

Supply the following if possible:
- RB951UI-2HnD
- Tried OpenWRT 19.07.1, 18.07.7 and lede 17.01.07
- Mac Address strts with 74:4D:28 (I include it because maybe it indicates a newer HW revisionthat needs to be supported)

Steps to reproduce
- Boot machine from network
- Flash image (tried 3 different versions, all same result)
- Wait for reboot to complete
- NOTE: LED 5 is red, I expect them to be green if network cable was connected, or off otherwise
- run `iw list` ⇒ Empty response
- Install pciutils (opkg install pciutils)
- run `lspci -nn` ⇒ Nothing is outputted
- run `cat /proc/cpuinfo` ⇒ Note the Mhz of the device is 299, while the device should be running at 600 Mhz

So to summarize
* LEDs aren’t working properly (or indicating its in a failed state, although I can’t find anything obvious in dmesg)
* WiFi isn’t working
* pci listing doesn’t work (maybe this device doesn’t have anything pci related, but I executed that command to debug the wifi issue)
* CPU is limited to 300 Mhz while it should be 600 Mhz (in dmesg I can actually see in the commandline it boots with MHZ=3000000, not sure how/if I can override or why the default would be 300

I confirm the issue with new hardware. Already posted on the forum and openwrt-devel list Forum Post

dmesg line:

[    0.000000] Kernel command line: benand_no_swecc=2 parts=1 boot_part_size=4194304 gpio=130619 HZ=300000000 mem=128M kmac=74:4D:28:F5:35:5E board=951HnD Board=951HnD board_rev=r2 ver=6.44.4 bver=6.43.2 hw_opt=00290005 boot=1 mlc=11 roo
tfstype=squashfs noinitrd

Various command outputs:

root@OpenWrt:~# iw dev wlan0 info
command failed: No such device (-19)

root@OpenWrt:~# dmesg | grep ath

I do not see ar934x_wmac in /sys/devices/platform on new hardware, but
it is present on older hardware.

Following line is missing in new hardware's dmesg, while presend in older hardware:
