Bryan O'Donoghue 852cc548b3 warp7: Set u-boot serial# based on OTP value
u-boot has a standard "serial#" environment variable that is suitable
for storing the iSerial number we will supply via the USB device
descriptor. serial# is automatically picked up by the disk subsystem in
u-boot - thus providing a handy unique identifier in /dev/disk/by-id as
detailed below.

Storing the hardware serial identifier in serial# means we can change the
serial# if we want before USB enumeration - thus making iSerial automatic
via OTP but overridable if necessary.

This patch reads the defined OTP fuse and sets environment variable
"serial#" to the value read.

With this patch in place the USB mass storage device will appear in
/dev/disk/by-id with a unique name based on the OTP value. For example

/dev/disk/by-id/usb-Linux_UMS_disk_0_WaRP7-0xf42400d3000001d4-0:0
