usb: typec: ucsi: fix tracepoint related build error
There is the following build error with CONFIG_TYPEC_UCSI=m, CONFIG_FTRACE=y
and CONFIG_TRACING=n:
ERROR: "__tracepoint_ucsi_command" [drivers/usb/typec/ucsi/typec_ucsi.ko] undefined!
ERROR: "__tracepoint_ucsi_register_port" [drivers/usb/typec/ucsi/typec_ucsi.ko] undefined!
ERROR: "__tracepoint_ucsi_notify" [drivers/usb/typec/ucsi/typec_ucsi.ko] undefined!
ERROR: "__tracepoint_ucsi_reset_ppm" [drivers/usb/typec/ucsi/typec_ucsi.ko] undefined!
ERROR: "__tracepoint_ucsi_run_command" [drivers/usb/typec/ucsi/typec_ucsi.ko] undefined!
ERROR: "__tracepoint_ucsi_ack" [drivers/usb/typec/ucsi/typec_ucsi.ko] undefined!
ERROR: "__tracepoint_ucsi_connector_change" [drivers/usb/typec/ucsi/typec_ucsi.ko] undefined!
This compination is quite hard to create because CONFIG_TRACING gets selected
only in rare cases without CONFIG_FTRACE.
The build failure is caused by conditionally compiling trace.c depending on
the wrong option CONFIG_FTRACE. Change this to depend on CONFIG_TRACING like
other users of tracepoints do.
Fixes: c1b0bc2dabfa ("usb: typec: Add support for UCSI interface")
