ANDROID: Fix qemu-minimal after upstream merge This fixes a serious problem on arm64 which is caused by CONFIG_BLK being changed to 'default y' if DM_MMC or DM_USB are set. After our minimal config neither of these are set on arm64, so BLK gets disabled unintentionally. Explicitly enable BLK. Also disable CONFIG_I2C which became 'default y' upstream, but we don't have an emulated I2C bus so this is pure bloat. Change-Id: I621f50610a0623595d8f858af4827a9d534cebba
