LF-7382: fastboot: improve emmc write speed 

tested at iMX8MM platfrom reduce almost half write time.
(499s vs 1000s).
About 1/4 improve at 8DXL platform.

100*512 = 51k, which small than emmc erase block size 64k,
which may cause more page management in emmc.

Increase to 4096, about 2M write to emmc each time.
