msm: mhi_dev: Do not enable aggregated MHI_A7 interrupt 



Do not enable the aggregated mhi_a7 irq, and avoid registering
for the corresponding callback if the separate mhi_a7 irq is
supported by the HW to avoid scheduling the workqueue twice for
a single occurrence of the interrupt and to avoid
unbalanced mhi irq enable.
