iommu/arm-smmu: Don't wipe out MICRO_MMU_CTRL while halting
The MICRO_MMU_CTRL register is used for halt control, but it also
contains some important configuration bits. Currently, when we request
a halt, we're wiping out all of the other bits in the register, losing
any previous configuration. Fix this by reading the value and OR'ing in
the bits we need.
