net: dhcp: add private extention 224 to pass the oftree file via dhcp.
DHCP option 224 to 254 are for private use, so use one.
Export it via env dhcp_oftree_file.
E.g. the ISC dhcp server can be configured with
| option oftree-path code 224 = string
| class "at91sam9x5ek" {
| match if substring (option vendor-class-identifier,0,20) = "barebox-at91sam9x5ek";
|
| filename "/tftpboot/atmel/at91sam9x5/sam9x5ek/zImage";
| option tftp-server-name "192.168.200.98";
| option root-path "192.168.200.98:/opt/work/buildroot/build/sam9x5/target";
| option oftree-path "/tftpboot/atmel/at91sam9x5/sam9x5ek/sam9g25ek/dtb";
| }
