There is no point to allow selecting clock controller drivers 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. 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.

Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx>

Changes since v1:
1. Correct pinctrl->clock in commit msg,
2. Do not restrict several drivers for older ARM64 SoCs to ARM64 only,
following the discussion. Argumentation from Stephen was that some
ARM64 SoCs could be used in arm32 emulation mode. This is heavily
unlikely for newer SoCs.
