usb: typec: ucsi: simplify command sending API

The sync_write and async_write are used only for writing UCSI commands
to the UCSI_CONTROL offsets. Rename sync_write and async_write
operations to sync_control and async_control accordingly. Drop the
offset and length fields and pass u64 command instead.
