device-xiaomi-santoni: use mdss-fb-init-hack to refresh the display, and
swapfile to fix "out of memory" when loading proprietary blobs.
I have tested the kernel, USB Networking, Display, USB OTG, Wi-Fi (with
proprietary blobs) works fine, through I haven't figured out how to get
Bluetooth and among of other stuff to work. Audio works. For more
information on how to get Wi-Fi and Audio to work, check out the wiki
page for this device, I have updated it.
