Several drivers check ->chipsize to see if the third row address cycle
is needed. Instead of embedding magic sizes such as 32MB, 128MB in
drivers, introduce a new flag NAND_ROW_ADDR_3 for clean-up. Since
nand_scan_ident() knows well about the device, it can handle this
properly. The flag is set if the row address bit width is greater
than 16.
Delete comments such as "One more address cycle for ..." because
intention is now clear enough from the code.

chip->bits_per_cell which is used to determine the NAND cell type
(SLC/MLC) should always have a value != 0.
Complain loudly if the value is 0 in nand_is_slc() to catch use before
correct initialization.

We are planning to share more code between different NAND based
devices (SPI NAND, OneNAND and raw NANDs), but before doing that
we need to move the existing include/linux/mtd/nand.h file into
include/linux/mtd/rawnand.h so we can later create a nand.h header
containing all common structure and function prototypes.
