Marek Vasut 41e30dcf87 cmd: mmc: Make Mode: printout consistent 
The "Mode :" line is the only one in "mmc info" output that has a
space in front of the colon. Drop the space to make it consistent
with the rest of the output, e.g.:

=> mmc dev 1 ; mmc info
switch to partitions #0, OK
mmc1 is current device
Device: sd@ee160000
Manufacturer ID: 3
OEM: 5344
Name: SL08G
Bus Speed: 50000000
Mode : SD High Speed (50MHz)
    ^------------------------------ Remove this space
Rd Block Len: 512
SD version 3.0
High Capacity: Yes
Capacity: 7.4 GiB
Bus Width: 1-bit
Erase Group Size: 512 Bytes
