[PATCH] drm/kmb: Remove unused const and defines

[linux@treblig.org]

From: "Dr. David Alan Gilbert" <linux@treblig.org>

layer_irqs[] was added in 2020 as part of
commit 7f7b96a8a0a1 ("drm/kmb: Add support for KeemBay Display")
but isn't used.

Remove it.

It was the only user of the LCD_INT_VL0, LCD_INT_VL1, LCD_INT_GL0
and LCD_INT_GL1 defines.

Remove them.

commit c026565fe9be ("drm/kmb: Enable alpha blended second plane")
added a second copy of the POSSIBLE_CRTCS define.

Remove it.
