sidk_s5jt200 : add romfs device automount support

This patch adds configuration and mount code for supporting
romfs device auto mount
If the romfs partition size and type and name are added in the
FLASH_PART_* configurtion and CONFIG_FS_ROMFS enabled,
a smart device(/dev/smart0pX) will be created and
romfs filesystem will be automounted on it.

To test it,
1. configure for sidk_s5jt200/hello_with_tash
2. make menuconfig
	- Enable CONFIG_FS_ROMFS
	- Split last partition size to (256,256) in CONFIG_SIDK_S5JT200_FLASH_PART_LIST
	- Append "smartfs" at the end to CONFIG_SIDK_S5JT200_FLASH_PART_TYPE
	- Append "romfs" at the end to CONFIG_SIDK_S5JT200_FLASH_PART_NAME
	  (Above 3 steps created romfs partition with size 256K at the end,
		where romfs device is a smart device and romfs filesystem will be
		mounted on smartdevice "/dev/smart0p15" )

	- Enable CONFIG_SIDK_S5JT200_AUTOMOUNT_ROMFS
3. make
4. Put "contents" into "external/contents" directory
4. make download ALL
