Subject: drm/msm/dpu: allow just single IRQ callback
Git-commit: c929ac60b3ed34accd25a052a4833e418900f466
Patch-mainline: v5.19-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
DPU interrupts code allows multiple callbacks per interrut. In reality
none of the interrupts is shared between blocks (and will probably never
be). Drop support for registering multiple callbacks per interrupt to
simplify interrupt handling code.
