FAT: Add FAT write feature
In some cases, saving data in RAM as a file with FAT format is required.
This patch allows the file to be written in FAT formatted partition.
The usage is similar with reading a file.
First, fat_register_device function is called before file_fat_write function
in order to set target partition.
Then, file_fat_write function is invoked with desired file name,
start ram address for writing data, and file size.
