On i.MX the SysTick IRQ cannot wake the CPU from a WFI so the CPU was blocked on WFI waiting for USB data in mp_hal_stdin_rx_chr() even though it had already arrived (because it may arrive just after calling the check tud_cdc_available()). This commit fixes this problem by using SEV/WFE to indicate that there has been a USB event. The mp_hal_stdout_tx_strn() function is also fixed so that it doesn't overflow the USB buffers.
