Subject: [PATCH v2 06/29] memory: Enable compile testing for most of the drivers

Most of the memory controller drivers do not depend on architecture
specific code so can be compile tested to increase build coverage.

When compile tested, do not enable them by default.

Signed-off-by: Krzysztof Kozlowski <krzk@...nel.org>

---

Changes since v1:
1. When compile tested, do not enable them by default.
