Built against tty-next commit: 1e619a1bf9ac878e6a984e4e279ccf712a65bc23
changes since v1: Move defines and add fail check to pci_ioremap_bar
This depends on my previous patch submissions:
[PATCH v3] Add support for new devices: Exar's XR17V35x family of
multi-port PCIe UARTs
[PATCH 1/2] tty/8250: Add sleep capability to XR17D15X ports
[PATCH 2/2] tty/8250 Add XR17D15x devices to the exar_handle_irq override
[PATCH 1/3] Add register definitions used in several Exar PCI/PCIe UARTs
