ARM: OMAP2+: fix build breakage introduced by commit b7754452b3e27716347a528b47b0a108...

Commit b7754452b3e27716347a528b47b0a1083af32520 ("mtd: onenand: omap:
use pdata info instead of cpu_is") broke an OMAP3+4 build and an N800
multi-OMAP2xxx build here:

drivers/built-in.o: In function `omap2_onenand_probe':
drivers/mtd/onenand/omap2.c:742: undefined reference to `omap2_onenand_read_bufferram'
drivers/mtd/onenand/omap2.c:743: undefined reference to `omap2_onenand_write_bufferram'
drivers/mtd/onenand/omap2.c:742: undefined reference to `omap2_onenand_read_bufferram'
drivers/mtd/onenand/omap2.c:743: undefined reference to `omap2_onenand_write_bufferram'

...

drivers/built-in.o: In function `omap2_onenand_probe':
drivers/mtd/onenand/omap2.c:788: undefined reference to `omap3_onenand_read_bufferram'
drivers/mtd/onenand/omap2.c:788: undefined reference to `omap3_onenand_write_bufferram'

Fix by declaring static functions for the missing symbols, rather than
just prototypes.
