Subject: [PATCH] arm64: defconfig: Enable TISCI Interrupt Router and Aggregator

Enable TISCI Interrupt Router and Interrupt Aggregator drivers.
These IPs are found in all TI K3 SoCs like J721E, AM62X and is required
for core functionality like DMA, GPIO Interrupts which is necessary
during boot, thus make them built-in.

Previously both of these configs were selected for ARCH_K3 in respective
Kconfigs, but commit b8b26ae398c4 ("irqchip/ti-sci-inta : Add module build support")
and commit 2d95ffaecbc2 ("irqchip/ti-sci-intr: Add module build support")
in linux-next dropped this recently without adding those back in arm64
defconfig, this causes boot failure in all TI K3 platforms.

Passing bootlog with configs enabled:

In above run I had to revert commit ba5095ebbc7a ("mfd: syscon: Allow syscon nodes without a "syscon" compatible")
also to fix an unrelated issue.
