lib/bootconfig: narrow flag parameter type from uint32_t to uint16_t

Browse Source 
The flag parameter in the node creation helpers only ever carries
XBC_KEY (0) or XBC_VALUE (0x8000), both of which fit in uint16_t.
Using uint16_t matches the width of xbc_node.data where the flag is
ultimately stored.
