This patch fixes probe failure in non-DT cases by adding appropriate resource names to fimd0 platform device.

Incorrectly specified UART port results in system getting stalled while printing the message "Uncompressing Linux... done, booting the kernel" This UART port number is specified through S3C_LOWLEVEL_UART_PORT. Since the UART port might different for different board, it is not possible to specify it correctly for every board that use a common defconfig file. Calling this print subroutine only when DEBUG_LL fixes the problem. By disabling DEBUG_LL in default config file, we would be able to boot multiple boards with different default UART ports. With this current approach, we miss the print "Uncompressing Linux... done, booting the kernel." when DEBUG_LL is not defined.
