Subject: [PATCH v2] usb: add missing MODULE_DESCRIPTION() macros

With ARCH=x86, make allmodconfig && make W=1 C=1 reports:
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/usb/core/usbcore.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/usb/mon/usbmon.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/usb/class/usbtmc.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/usb/storage/uas.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/usb/chipidea/ci_hdrc_msm.o

Add the missing invocations of the MODULE_DESCRIPTION() macro.

This is the remaining one-off fixes in usb.

Corrections to these descriptions are welcomed. I'm not an expert in
this code so in most cases I've taken these descriptions directly from
code comments, Kconfig descriptions, or git logs.  History has shown
that in some cases these are originally wrong due to cut-n-paste
errors, and in other cases the drivers have evolved such that the
original information is no longer accurate.

Let me know if any of these changes need to be segregated into
separate patches to go through different maintainer trees.
