accel/qaic: Allocate an exact number of MSIs
Devices use 1 MSI vector for the MHI controller and as many vectors as
the DMA bridge channels on the device. During the probing of the
device, the driver allocates 32 MSI vectors, which is usually more
than what is needed for AIC100 devices, which is wasting resources.
Allocate only the needed number of MSI vectors per device.
