PCI: dwc: Makefile/Kconfig: sort alphabetically

Commit Message

Han Jingoo Jan. 16, 2020, 9:47 p.m. UTC

The order in dwc directory is PCIE_DW, PCI_*, and PCIE_* as below.

1. Common Frameworks:
    These options are used by other controller drivers.
    e.g., PCIE_DW, PCIE_DW_HOST, PCIE_DW_EP.

2. PCI_* controller drivers:
    PCI_* was used earlier than PCIE_*. If a chip vendor's controllers provide
    both conventional PCI and PCI Express, or only conventional PCI, PCI_* can
    be used.

3. PCIE_* controller drivers:
    If a controller can support only PCI Express, not conventional PCI,
    PCIE_* is the proper naming.

Then, within PCI_* or PCIE_* categories, each controller option should be
in an alphabetical order for the readability.
