[PATCH 0/2] PCI: dwc: Make the MSI domain naming explicit

[Shawn Lin <shawn.lin@rock-chips.com>]

I was looking into whether the DWC core provides a common INTx irq
domain registration and handling flow, as several glue drivers owning
a legacy interrupt controller copy-paste the same code (get the
"legacy-interrupt-controller" child node, create a linear domain with
a one-line .map callback, install a chained handler).

The DWC core has no INTx equivalent at all: dw_pcie_allocate_domains()
looks like it could be that helper at first glance, but it only
creates the MSI parent irq domain (msi_create_parent_irq_domain() with
DOMAIN_BUS_PCI_MSI). Likewise, struct dw_pcie_rp::irq_domain only
serves the MSI parent domain.

So make the naming explicit:

patch 1 renames dw_pcie_allocate_domains() to
dw_pcie_allocate_msi_domains().

patch 2 renames struct dw_pcie_rp::irq_domain to ::msi_irq_domain.
