davinci: DA8XX/OMAP-L1XX: fix compiler warning

When kernel is built with CONFIG_DEBUG_SECTION_MISMATCH=y
option, using da8xx_omapl_defconfig, some warnings are
observed:

WARNING: vmlinux.o(.text+0xc2a4): Section mismatch in reference
from the function da850_evm_setup_nor_nand() to the variable
.init.data:da850_nand_pins
The function da850_evm_setup_nor_nand() references
the variable __initdata da850_nand_pins.
This is often because da850_evm_setup_nor_nand lacks a __initdata
annotation or the annotation of da850_nand_pins is wrong.

This patch fixes such warnings.
