Dear Jim Lin,

> TFTP booting is slow when a USB keyboard is installed and
> stdin has usbkbd added.
> This fix is to change Ctrl-C polling for USB keyboard to every second
> when NET transfer is running.

> Changes in v2:
>  1. Change configuration name from CONFIG_CTRLC_POLL_MS to
> CONFIG_CTRLC_POLL_S. 2. New code will be executed only when
> CONFIG_CTRLC_POLL_S is defined in configuration header file.
>  3. Add description in README.console.
> Changes in v3:
>  1. Move changes to common/usb_kbd.c and doc/README.usb
>  2. Rename config setting to CONFIG_USBKB_TESTC_PERIOD.
>  3. Remove slow response on USB-keyboard input when TFTP boot is not
> running. Changes in v4:
>  1. Remove changes in doc/README.usb, common/usb_kbd.c and
>     CONFIG_USBKB_TESTC_PERIOD
>  2. Modify net/net.c
> Changes in v5:
>  1. Change variable name to ctrlc_t_start.
>  2. Use two calls of get_timer(0) to get time gap.
> Changes in v6:
>  1. In common/usb_kbd.c, check net_busy_flag to determine whether we poll
>     USB keyboard status.
>  2. In include/usb.h, add external variable declaration net_busy_flag
> Changes in v7:
>  1. In common/usb_kbd.c and include/usb.h, add #ifdef CONFIG_CMD_NET.
>  2. In common/usb_kbd.c, modify code to get correct time gap.
> Changes in v8:
>  1. Add __maybe_unused for variable kbd_testc_tms.
> Changes in v9:
>  1. Move external variable declaration from include/usb.h to
