Subject: [PATCH v3 2/4] PCI: dwc: Export dw_pcie_allocate_domains() and dw_pcie_ep_raise_msix_irq()

The pci-keystone.c driver uses the functions 'dw_pcie_allocate_domains()'
and 'dw_pcie_ep_raise_msix_irq()'. In preparation for enabling the
pci-keystone.c driver to be built as a loadable module, export them.

This patch is a combination of patches 02/10 and 04/10 of the v2 series:
02/10: https://lore.kernel.org/r/20250912122356.3326888-3-s-vadapalli@ti.com/
04/10: https://lore.kernel.org/r/20250912122356.3326888-5-s-vadapalli@ti.com/
Except for merging the patches of the v2 series together, and updating the
commit message, no other changes have been made to get to this v3 patch.
