cmd_nand: show nand scrub confirmation character
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. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com>
