[PATCH] PCI: eswin: Publish the platform driver's OF alias

[PATCH] PCI: eswin: Publish the platform driver's OF alias

[hpp.iscas]

The ESWIN PCIe host controller is a platform driver matched through
eswin_pcie_of_match. PCIE_ESWIN is tristate, but the table is not
published for OF module autoloading.

Publish this platform-device table. Do not change the RISC-V host
initialization sequence or PCI device matching.

Hi hpp.iscas

Since this driver uses `builtin_platform_driver(eswin_pcie_driver)`, it
appears to be built-in only. In that case, `MODULE_DEVICE_TABLE()` seems
unnecessary.

Nope. builtin_platform_driver() only prevents removing the driver once loaded.
Since the driver is defined as 'tristate' in Kconfig, it can still be loaded
dynamically. So MODULE_DEVICE_TABLE() would still be necessary for udev to
autoload the module based on modalias.

As per Linux Kernel DCO, a real name is required for the submitter/author.
Please refer: Documentation/process/submitting-patches.rst

'hpp.iscas' doesn't appear to be a real name.
