Subject[PATCH v2 8/9] ath10k: Use pci_enable_msi_range()
Date
As result deprecation of MSI-X/MSI enablement functions
pci_enable_msix() and pci_enable_msi_block() all drivers
using these two interfaces need to be updated to use the
new pci_enable_msi_range() and pci_enable_msix_range()
interfaces.

This update also fixes a stylistic (naming and messaging only)
confusion of MSI-X vs multiple MSIs which are not the same.
