[PATCH 3/4] soc: qcom: Make important drivers default

[Krzysztof Kozlowski <krzysztof.kozlowski@oss.qualcomm.com>]

The drivers for Qualcomm SoC components are covering a basic or
fundamental SoC blocks.  Usually they are required for booting or to
achieve basic expected functionality when running Linux.  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 most of the Qualcomm SoC drivers to a default 'yes' or
'module' for ARCH_QCOM, to match existing defconfig usage.

This has no impact on arm64 defconfig, arm qcom_defconfig and arm
multi_v7_defconfig.

The change will however enable by default all drivers for arm or arm64
COMPILE_TEST builds, whenever ARCH_QCOM is selected, which feels
logical: 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.
