of: base: use root_node compatible as suggestion for a hostname
on some SoCs we can use generic PLL and RAM initialization. In this cases we create board file only to provide a host name. With this patch host name will be created from device tree compatible. For example: compatible = "board_vendor,board", "chip_vendor,soc" the host name will be: "board" This function will not overwrite a host name which is already set by board or machine code.
