android: add sunxi IR remote profile

[danielcamposramos]

Summary

Add an Android menu-navigation profile for the Allwinner built-in IR receiver
that reports:

Device: sunxi-ir-uinput
VID:    0x0000 / 0
PID:    0x0000 / 0
Source: DPAD | KEYBOARD (0x00000301)

The repository already has sunxi-ir.cfg, but Android treats
sunxi-ir-uinput as a different exact input device, so that profile does not
match this receiver.

Hardware validation

• Android 10 TV box using an Allwinner H616 SoC.
• Physical bundled IR remote.
• Android's active /system/usr/keylayout/sunxi-ir-uinput.kl maps Back,
  D-pad directions, D-pad Center, and Menu to keycodes 4, 19–23, and 82.
• The physical remote was confirmed navigating RetroArch with arrows, OK,
  Back, and Menu.
• The profile deliberately includes only those validated menu functions.
• Repository test result: No duplicate profiles were found.

HDMI-CEC is intentionally excluded: on this Android build CEC events are
framework-injected as deviceId=-1, SOURCE_HDMI, with no physical device
name or VID/PID, so they cannot be represented honestly by a joypad
autoconfiguration profile.
