Subject: [PATCH v9 13/13] arm64: defconfig: enable SHM Bridge support for the TZ memory allocator

From: Bartosz Golaszewski <bartosz.golaszewski@...aro.org>

Enable SHM Bridge support in the Qualcomm TrustZone allocator by default
as even on architectures that don't support it, we automatically fall
back to the generic allocator.
