uboot-config.bbclass: Allow multiple U-Boot config for machine

Browse Source 
This adds support to build multiple U-Boot configs for a machine; this
  is useful when we have support for different media boots which require
  different U-Boot configuration (e.g: eMMC and NAND).

  Below there's an usage example:
  ,----[ i.MX6Q SABRE AUTO based example ]
  | UBOOT_CONFIG ??= "sd eimnor nand spinor"
  | UBOOT_CONFIG[sd] = "mx6qsabreauto_config,sdcard"
  | UBOOT_CONFIG[eimnor] = "mx6qsabreauto_eimnor_config"
  | UBOOT_CONFIG[nand] = "mx6qsabreauto_nand_config,ubifs"
  | UBOOT_CONFIG[spinor] = "mx6qsabreauto_spinor_config"
  `----
