There are multiple reasons why this define should be removed:
First it saves some space and therefore fixes a problem we have on
the canyonlands_nand and glacier_nand targets right now.
Second, the define was hackish and would most likely not work on all
board using nand_boot.c. Boards not providing a real dev_ready()
function should implement a board specific function instead.
I checked and it seems, that all boards using nand_boot.c right now
already implement a board specific dev_ready() function. So this
patch should not break any boards and will result in smaller
NAND_SPL images.

Handle most LDSCRIPT setting centrally

Some are found using CONFIG_SYS_LDSCRIPT, but the code for that is
sometimes in arch config.mk and sometimes in board config.mk. Some

Further, the powerpc config.mk rule relied on CONFIG_NAND_SPL
when it really wanted CONFIG_NAND_U_BOOT -- which covered up the fact
that not all NAND_U_BOOT builds actually wanted CPUDIR/u-boot-nand.lds.
Replace all of this -- except for a handful of boards that are actually
selecting a linker script in a unique way -- with centralized ldscript
finding.
If board code specifies LDSCRIPT, that will be used.
Otherwise, if CONFIG_SYS_LDSCRIPT is specified, that will be used.
If neither of these are specified, then the central config.mk will
check for the existence of the following, in order:
$(TOPDIR)/board/$(BOARDDIR)/u-boot-nand.lds (only if CONFIG_NAND_U_BOOT)
$(TOPDIR)/$(CPUDIR)/u-boot-nand.lds (only if CONFIG_NAND_U_BOOT)
$(TOPDIR)/board/$(BOARDDIR)/u-boot.lds
