Lioncash e32bf646cf yuzu/bootmanager: Treat the resolution factor as a u32
Treating it as a u16 can result in a sign-conversion warning when
performing arithmetic with it, as u16 promotes to an int when aritmetic
is performed on it, not unsigned int.

This also makes the interface more uniform, as the layout interface now
operates on u32 across the board.
