[U-Boot] [PATCH v2] fdt_support: Check for bank size before updating memory node

[Lokesh Vutla]

In case if one of the bank that is passed is of size zero, then u-boot
will be updating memory node with a bank of size zero. There is no need
to update memory node if size is zero, so check for bank size before
updating.
