iommu/arm-smmu: convert domain spinlock to a mutex
We'd like to use the domain lock to protect against a race condition
where the domain's device pointer is used after the domain has been
detached from the device. In order to prepare for this, change the
domain lock to a mutex, since we'll be holding during times where we
need to do non-atomic operations (like enabling clocks).
