Xiaomi Mi TV Stick is a small Amlogic-based Android TV stick released in
2020.  It is known as `xiaomi-aquaman` internally.  Specifications:
 * Amlogic S805Y SoC
 * Android TV 9, upgradable to Android TV 10
 * 8 GB eMMC
 * 1 GB of RAM
 * Wi-Fi + Bluetooth

The devicetree is based on p241's DT, with some changes to better match
the Mi TV Stick:
 * there is no Ethernet port, no IR, no CVBS connector on the stick
 * a white LED is present
 * adjust memory to have 1 GB of RAM available
