Davinci 8xx: Move common functions to share code
As more Davinci 8xx board can be added, move common code
to be shared between boards.
* rebased ontop of Sugosh's patches
* moving the HAWKBOARD_KICK{0,1}_UNLOCK defines to
arch/arm/include/asm/arch-davinci/davinci_misc.h from to
arch/arm/include/asm/arch-davinci/da8xx_common.h
* don't define dram functions in PRELOADER
* move sync_env_enetaddr into existing EMAC ifdef
* use misc.c in hawkboard nand_spl
