[U-Boot] [PATCH] cmd_nand: show nand scrub confirmation character

[Florian Fainelli]

When issuing a nand scrub command, the entered character is not displayed
this may be confusing. This patch makes the input character being displayed
if it is a 'y' so that an user knows he is about to scrub his nand.
