Enable clock controller, interrconnect and pinctrl for QCS8300.
It needs to be built-in for UART to provide a console.

NXP QCS8300? What is QCS8300? Which products use it? That's a defconfig
for entire kernel, not your Qualcomm one.

Why this cannot be a module?

I think the commit-msg "It needs to be built-in for UART to provide a console." can
explain that, could you please help to share your insights on that?

Unless loading these modules from initramfs doesn't work, please use =m.
The drivers that are enabled here are going to be enabled for everybody
using arm64 defconfig, taking up memory on their platforms, etc.

We had previous discussion here about why these drivers needs to be built-in to support
debug-uart:
https://lore.kernel.org/linux-arm-msm/c11fd3c2-770a-4d40-8cf3-d8bc81f7c480@kernel.org/
I will mention more details in the commit message of this patch.

Yes, please. Explicitly mention that this is required to get UART to work.
