u-boot: extend UBOOT_CONFIG format to support different binary name
When using UBOOT_CONFIG format, the final u-boot binary for each config
may have different names. Extend UBOOT_CONFIG format to support different
binary to be copied.
The new format is supposed to be compatible with old one as ${UBOOT_BINARY}
is copied by default, and images,binary can be empty.
An example format to specify it, in the machine, is:
UBOOT_CONFIG ??= "sdcard-ifc sdcard-qspi lpuart qspi secure-boot nor"
UBOOT_CONFIG[nor] = "ls1021atwr_nor_config,,u-boot-dtb.bin"
UBOOT_CONFIG[sdcard-ifc] = "ls1021atwr_sdcard_ifc_config,,u-boot-with-spl-pbl.bin"
UBOOT_CONFIG[sdcard-qspi] = "ls1021atwr_sdcard_qspi_config,,u-boot-with-spl-pbl.bin"
UBOOT_CONFIG[lpuart] = "ls1021atwr_nor_lpuart_config,,u-boot-dtb.bin"
UBOOT_CONFIG[qspi] = "ls1021atwr_qspi_config,,u-boot-dtb.bin"
UBOOT_CONFIG[secure-boot] = "ls1021atwr_nor_SECURE_BOOT_config"
