Andrei Kuchynski 9fc83373f0 platform/chrome: cros_ec_typec: Add support for setting USB mode via sysfs ...

This patch implements USB mode setting via a sysfs interface in
cros_ec_typec driver. User-space applications can now change the current
USB mode by writing to "usb_mode" sysfs entry, replacing the previous
ioctl-based method.
The embedded controller (EC) currently supports only entering USB4 mode
and exiting all modes (including altmodes). Both of these operations
trigger Data Reset Message, even if no USB Mode is active.
Additionally, the patch exposes the USB modes supported by the port via
"usb_capability" sysfs attribute.
