Register a power supply charger, whose online state depends on whether
the USB role is set to device or not.
This is useful when the USB role is the only way to know if the device
is charging from USB. The API is the standard power supply charger API,
you get a /sys/class/power_supply/xxx/online node which tells you the
state of the charger.
The sole purpose of this is to give userspace applications a way to
know whether or not the charger is plugged.

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.
Deterministic algorithm:
For each file:
If not .svg:
For each line:
If doesn't contain `\bxmlns\b`:
For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
If both the HTTP and HTTPS versions
return 200 OK and serve the same content:
Replace HTTP with HTTPS.

Firstly, demote function header to standard comment block as
they are not suitable for kerneldoc. Then provide description
for ulpi_register_driver()'s argument 'module'. Finally rename
description for ulpi_unregister_interface()'s 'ulpi' arg.
Fixes the following W=1 warnings:

Patch moves some decoding functions from driver/usb/dwc3/debug.h driver
to driver/usb/common/debug.c file. These moved functions include:
dwc3_decode_get_status
dwc3_decode_set_clear_feature
dwc3_decode_set_address
dwc3_decode_get_set_descriptor
dwc3_decode_get_configuration
dwc3_decode_set_configuration
dwc3_decode_get_intf
dwc3_decode_set_intf
dwc3_decode_synch_frame
dwc3_decode_set_sel
dwc3_decode_set_isoch_delay
dwc3_decode_ctrl
These functions are used also in inroduced cdns3 driver.
All functions prefixes were changed from dwc3 to usb.
Also, function's parameters has been extended according to the name
of fields in standard SETUP packet.
Additionally, patch adds usb_decode_ctrl function to
include/linux/usb/ch9.h file.

The USB gadget subsystem wants to use the USB debugfs root directory, so
move it to the common "core" USB code so that it is properly initialized
and removed as needed.
In order to properly do this, we need to load the common code before the
usb core code, when everything is linked into the kernel, so reorder the
link order of the code.
Also as the usb common code has the possibility of the led trigger logic
to be merged into it, handle the build option properly by only having
one module init/exit function and have the common code initialize the
led trigger if needed.

In some places, the code prints a human-readable USB endpoint
transfer type (e.g. "bulk"). This involves a switch statement
sometimes wrapped around in ({ ... }) block leading to code
repetition.
To make this scenario easier, here introduces usb_ep_type_string()
function, which returns a human-readable name of provided
endpoint type.
It also changes a few places switch was used to use this
new function.
