[c-nsp] c7200 format bootflash: etc

[FreeLSD]

btw, seems 122-14.S15 and 122-18.S10 have broken format for bootflash: 
and card?:, because rommon cant read it after formating.
but after loading IOS card/bootflash can be perfectly readed/formated/writed.

reformating such cards with c7200-boot-mz.120-21.ST.bin have good result,
it can be readed by rommon. (success with slot?: cards. dont tryed for 
bootflash: case, because have no time... router in production :) 

workaround:
boot system disk1:c7200-p-mz.122-18.S10.bin
boot bootldr disk1:c7200-kboot-mz.122-18.S10.bin

ps. tested on two c72xx routers
