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>.

This is version 2 of the patch for removing the rd_size declaration.
Compared to v1, the new header file <linux/brd.h> has been dropped.
