Subject: [PATCH] PCI: uniphier: remove module code from built-in driver

builtin_platform_driver() and MODULE_* are always odd combination.

The MODULE_* tags are never populated since CONFIG_PCIE_UNIPHIER is
a bool option.

You can see similar cleanups by:
  git log --grep='explicitly non-modular'

Following those commits, remove all the MODULE_* tags and the driver
detach code.
