zephyr: wrapper: Conditionally call platform_boot_complete()

Due to the fact that on i.MX93 the host will initialize the
SOF_IPC_FW_READY sequence there's no need to call
platform_boot_complete() at the end of start_complete(). This
will be handled in the IPC3 handler.

This commit makes sure that aforementioned scenario won't
happen for i.MX93 while keeping the flow constant for the
other platforms.
