As part of the legacy from the original driver design, we retain home-grown
tracing infrastructure, complete with own ring buffer and timestamps,
which among other things has a performance penalty. This patch removes it.

debug.c is carrying a lot of includes that aren't needed there, although
they implicitly include the ones that are actually needed. Replace the
former with the latter.

The static lock initializers want to be fed the proper name of the
lock and not some random string. In mainline random strings are
obfuscating the readability of debug output, but for RT they prevent
the spinlock substitution. Fix it up.

This commit removes the /sys/devices/platform/<UDC>/udc/<UDC>/is_dualspeed
file and is_dualspeeed line from /sys/devices/platform/ci13xxx_*/udc/device
file.
The is_dualspeed file is superseded by maximum_speed in the same directory
and is_dualspeed line in device file is superseded by max_speed line in
the same file.
The maximum_speed/max_speed specifies maximum speed supported by UDC.
To check if dualspeeed is supported, check if the value is >= 3.
