851ce93224 usb: chipidea: otg: don't wait vbus drops below BSV when starts host
Some HW design may use ID pin state to control vbus for otg port,
so before host role start, the vbus is already turned on, in this
case, we do not need wait vbus dropping below BSV.

50bdb12388 usb/host/fotg210: Add function scan_frame_queue()
checkpatch complains about too many leading tabs because the if
statement starts after 6 tabs:

scan_iosoc() -> for() -> while() -> switch() -> if() -> for() -> if()

There is also a goto statement going backwards in case of failure. This
patch creates a new inline function named scan_frame_queue() containing
the last 4 nesting levels, and removes the need of backwards goto,
making the code easier to read. After the patch it becomes:

scan_iosoc() -> for() -> while() -> scan_frame_queue()

checkpatch complains about too many leading tabs because the switch
statement starts after 6 tabs.

05ebc36e48 usb/host/fotg210: replace msleep by usleep_range
msleep under 20ms can result in sleeping up to 20ms, which may not be
intended. Replace msleep(5) by usleep_range(5000, 10000). The range of 5
ms is to reduce the chances of creating an interrupt while reducing the
maximum wait time in 50%.

Provide the methods to let ACPI identify the need to use
xhci-platform. Change the Kconfig files so the
xhci-plat.o file is selectable during kernel config.

This has been tested on an ARM64 machine with platform XHCI, an
x86_64 machine with XHCI, and an x86_64 machine without XHCI.
There were no regressions or error messages on the machines
without platform XHCI.

The xhci platform driver needs to work on systems that

Attempt to set a coherent dma mask for 64-bit DMA, and
