Rename STANDALONE_LOAD_ADDR into CONFIG_STANDALONE_LOAD_ADDR
and allow that the architecture-specific default value gets
overwritten by defining the value in the board header file.

Note that some architectures (blackfin, coldfire, mips, sh, sparc)
misuse the CONFIG_STANDALONE_LOAD_ADDR variable to not only specify
the load address (as the name suggests), but also to supply additional
linker options:
arch/blackfin/config.mk:CONFIG_STANDALONE_LOAD_ADDR ?= 0x1000 -m elf32bfin
arch/m68k/config.mk:CONFIG_STANDALONE_LOAD_ADDR ?= 0x20000 -L $(clibdir)
arch/mips/config.mk:CONFIG_STANDALONE_LOAD_ADDR ?= 0x80200000 -T mips.lds
arch/sh/config.mk:CONFIG_STANDALONE_LOAD_ADDR += -EB
arch/sparc/config.mk:CONFIG_STANDALONE_LOAD_ADDR ?= 0x00000000 -L $(gcclibdir)
-T sparc.lds
Please clean this up! Thanks -- wd
