[U-Boot] [PATCH] spl: avoid printf when we might be doing Ymodem with CONFIG_SPL_FIT_SIGNATURE

[Alex Kiernan]

If CONFIG_SPL_FIT_SIGNATURE is enabled and U-Boot is being loaded from UART
over Ymodem then we can't emit messages using printf() without causing
errors like:

  Sending: u-boot-dtb.img
  Ymodem sectors/kbytes sent: 3009/376kRetry 0: Got 23 for sector ACK
  Retry 0: NAK on sector
  Retry 0: Got 68 for sector ACK
  Retry 0: NAK on sector
  Ymodem sectors/kbytes sent: 3273/409kRetry 0: Got 23 for sector ACK
  Retry 0: NAK on sector
  Retry 0: Got 68 for sector ACK
  Retry 0: NAK on sector

Use debug() rather than printf() to avoid sending messages on the serial
port.
