usb: gadget: fastboot: Add fastboot erase
Adds the fastboot erase functionality, to erase a partition
specified by name. The erase is performed based on erase group size,
to avoid erasing other partitions. The start address and the size
is aligned to the erase group size for this.
Currently only supports erasing from eMMC.
