[U-Boot] : Enhancement request to get flash device specific information

> SF : Detected N25Q128A with page size 256 Bytes, erase size 64 KiB, total
> 16 MiB

> Similarly I found there is command "nand info" for nand device which is
> also returning device properties into text format.

>
> Let say we includes following commands:
> "nand info pagesize/sectorsize/size/device"
> "sf info pagesize/sectorsize/size/device"
>
> for example:
> "nand info pagesize" command should return page size ( e.g. *256*)
> "nand info sectorsize" command should return sector size (e.g. *65536*
>  which is 64K)
> "nand info size" command should return the total size (e.g.  *268435456 *which
> is 16 MB)
