Similarly to clocks and pinctrl, interconnects should not be a user
visible choice.

Best regards,

KConfig entries should be indented starting with one tab, so replace
spaces with it.

There is no point to allow selecting core SoC drivers like interconnects
for Qualcomm ARMv7 SoCs when building ARM64 kernel, and vice versa.

This makes kernel configuration more difficult as many do not remember
the Qualcomm SoCs model names/numbers and their properties like
architecture.  No features should be lost because:
1. There won't be a single image for ARMv7 and ARMv8/9 SoCs.
2. Newer ARMv8/9 SoCs won't be running in arm32 emulation mode.

The interconnect drivers for Qualcomm SoC Network-on-Chip are covering a
basic or fundamental SoC feature: bandwidth management between internal
SoC blocks.  SoC can boot without these, but power management or
performance will be affected.  These drivers do not represent any sort
of buses visible to the board designers/configurators, thus they should
be always enabled, regardless how SoC is used in the final board.

Kernel configuration should not ask users choice of drivers when that
choice is obvious and known to the developers that answer should be
'yes' or 'module'.

Switch all almost Qualcomm interconnect drivers to a default 'yes' for
ARCH_QCOM.  This has impact:

1. arm64 defconfig: enable as built-in INTERCONNECT_QCOM_SDM660,
   INTERCONNECT_QCOM_SDM670, INTERCONNECT_QCOM_SM7150 and
   INTERCONNECT_QCOM_SAR2130P, which were not selected before but should
   be, because these platforms need them anyway.

2. arm qcom_defconfig: no changes.

3. arm multi_v7 defconfig: enable as modules drivers necessary to boot
   ARM 32-bit platforms, which are already enabled on qcom_defconfig:
   QCOM_RPMH, INTERCONNECT_QCOM_BCM_VOTER, INTERCONNECT_QCOM_MSM8974 and
   INTERCONNECT_QCOM_SDX55.

4. COMPILE_TEST builds: enable by default all drivers for arm or arm64
   builds, whenever ARCH_QCOM is selected.  This has impact on build
   time and feels logical, because if one selects ARCH_QCOM then
   probably by default wants to build test it entirely.  Kernels with
   COMPILE_TEST are not supposed to be used for booting.

I propose the change to go via interconnect tree.  It might conflict
around defconfigs, though.

I'd say let's make them all `default ARCH_QCOM` - all of these drivers
are required to boot (minus the OSM_L3 driver which is "only" highly
desired, so that your CPU's bus isn't heavily bottlenecked)

So the few of them should not be a module? That's what you want to say?
