sparc: leon3: Clear GD_FLAG_SERIAL_READY flag on AMBA failure
Clear the GD_FLG_SERIAL_READY flag on AMBA P&P lookup failure so that the panic function can use DEBUG_UART driver. drivers/serial/serial.c set this flag before calling this function, preventing DEBUG_UART code from running. Signed-off-by: Francois Retief <fgretief@spaceteq.co.za>
