Nicolas Boichat 19aace4ec0 host_command: Throttle printing of "+" for repeated commands ...

When AP boots and FW screen is shown (e.g. in developer mode),
AP FW is querying MKBP status in a loop, leading to a lot of "+"
being printed in the EC console.

To avoid this issue, let's print "(++)" after a command is received
5 times in a row.

BRANCH=none
BUG=b:37925684
TEST=Set GBB flags to 0x4a38, reasonable number of "+" is printed
     on EC console on boot, which firmware screen is being shown.
