ARM: OMAP1: board files: deduplicate and clean some NAND-related code

The H2, H3, Perseus2, and FSample board files all contain the same
duplicated code to handle NAND commands.  That code is missing
some casts around conversions from unsigned long to void __iomem *.

Consolidate the duplicated code into a new file,
arch/arm/mach-omap1/board-nand.c.  Resolve the sparse warnings by
adding appropriate casts:

arch/arm/mach-omap1/board-h2.c:193:9: warning: incorrect type in argument 1 (different base types)
arch/arm/mach-omap1/board-h2.c:193:9:    expected void const volatile [noderef] <asn:2>*<noident>
arch/arm/mach-omap1/board-h2.c:193:9:    got unsigned long

arch/arm/mach-omap1/board-fsample.c:199:9:    got unsigned long
arch/arm/mach-omap1/board-h3.c:195:9: warning: incorrect type in argument 1 (different base types)
arch/arm/mach-omap1/board-h3.c:195:9:    expected void const volatile [noderef] <asn:2>*<noident>
arch/arm/mach-omap1/board-h3.c:195:9:    got unsigned long

Thanks to Arnd Bergmann <arnd@arndb.de> for suggesting a cleaner
implementation of omap1_nand_cmd_ctl(), avoiding some casts.
