ARM: fix rd_size declaration
The global variable 'rd_size' is declared as 'int' in source file arch/arm/kernel/atags_parse.c and as 'unsigned long' in drivers/block/brd.c. Fix this inconsistency. Additionally, remove the declarations of rd_image_start, rd_prompt and rd_doload from parse_tag_ramdisk() since these duplicate existing declarations in <linux/initrd.h>.
