if udc-core always does it, we can delete
some extra lines from all UDC drivers. Besides,
it avoids mistakes from happening and propagating.

This driver can compile in any arch quite
easily by just removing a few headers and
dropping cpu_is_* check from module_init.

when commit 388e5c51 (usb: dwc3: remove dwc3
dependency on host AND gadget.) changed the
way debugfs files are created, it failed to
note that 'mode' is necessary in Dual Role
mode only while 'testmode' and 'link_state'
are valid in Dual Role and Peripheral-only
builds. Fix this while also converting pre-
processor conditional to C conditionals.
Signed-off-by: NFelipe Balbi <balbi@ti.com>

nobody should be modifying that structure and
debugfs has already being fixed to take const
arguments, so we won't cause any new compile
warnings.

whenever we grab an unknown link_state we
were printing the entire register value as
a integer but that's hardly useful; instead,
let's print only the bogus state value.

for Reset and Resume we were going to print
"UNKNOWN" when we actually knew what those

by moving to threaded IRQs, we allow our IRQ
priorities to be configurable when running with
realtime patch. Also, since we're running in
thread context, we can call functions which
might sleep, such as sysfs_notify() without
problems.

we can cache the last read value of the event
buffer count register on this field, for later
handling.

that way we know if a particular event buffer
has pending events, or not.

patch just removes its documentation.
