Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20191022-2' into staging

 * Fix sign-extension for SMLAL* instructions
 * Various ptimer device conversions to new transaction API
 * Add a dummy Samsung SDHCI controller model to exynos4 boards
 * Minor refactorings of RAM creation for some arm boards
