iommu: msm: Refactor remote spinlock defconfig
Refactor the remote spinlock defconfig to allow it to be used with
subsystems other than GPU. This will enhance the usability of this
feature and minimize the chance of errors when enabling this feature.

Say Y here if you want to synchronize access to IOMMU configuration
port between CPU and GPU. CPU will grab a remote spinlock before
