Fixed bug 3424 - SDL_GameController: Increase k_nMaxReverseEntries

ny00

On Android, the keycodes KEYCODE_BUTTON_1..16 (actual values 188-203) are translated to SDL_Joystick buttons no. 20-35. These are currently ignored in SDL_gamecontroller.c.

The attached patch fixes this, by increasing k_nMaxReverseEntries from 20 to another arbitrary bound of 48.

Side-note: Maybe some log should be emitted in case of going over any such bound?
