unneeded 3secs delay

You should remove the delay from the main thread: https://github.com/Princess-of-Sleeping/PSP2-CustomBootSplash/blob/master/src/main.c#L70

and instead create a thread

In the case of PS TV, if you do not delay for about 3 seconds, Boot Splash will only be displayed for a moment.

So add: if !(sceAIMgrIsDolce()) // delay();

In the case of h-encore too, if you do not delay for about 3 seconds, Boot Splash will only be displayed for an instant. So PS Vita also needs a delay.
