No file should be explicitly referencing its own platform headers
by specifying an absolute include path. Fix these paths to use
standard <asm/arch/...> includes.

As reported by Adrian Bunk, commit d5686b444f
(switch mtd and dm-table to lookup_bdev()) causes the following compile
error with CONFIG_BLOCK=n:
CC drivers/mtd/mtdsuper.o
drivers/mtd/mtdsuper.c: In function `get_sb_mtd':
drivers/mtd/mtdsuper.c:184: error: implicit declaration of function 'lookup_bdev'
drivers/mtd/mtdsuper.c:184: warning: assignment makes pointer from integer without a cast
drivers/mtd/mtdsuper.c:197: error: implicit declaration of function 'bdput'
make[3]: *** [drivers/mtd/mtdsuper.o] Error 1
Fix it by putting the block device lookup inside #ifdef CONFIG_BLOCK

The wrong version of the "teach dataflash about binary density" patch
just got merged (v2 not v3) ... this restores the missing updates:
* Fix the cmdlinepart *regression* that caused testing failures (!!)
by restoring the original part labels in relevant cases.
* Don't reference things that don't exist (!)
- An opcode that doesn't even exist for DataFlash
- The part is "at45db642" not "at45db641"
- ID zero in this JEDEC table
* Make the JEDEC probe routine report and handle errors better:
- If the SPI calls fail, return the error codes.
- Don't depend on ordering of table entries.
- Unrecognized ids are different from parts that have no ID.
We won't actually know how to handle them correctly; display
the ID and ignore the chip.
* Move the original block comment about the "legacy" chip ID scheme
back next to the code to which it applies ... not next to the new
JEDEC query code, which uses an entirely different strategy.
* Don't print a guessed erasesize; /proc/mtd has the real value.
And add a few more comments.

Commit 3d45955962 ("subpage read feature

support the "random page read" NAND command. This patch adds
corresponding support.

This patch enables NAND subpage read functionality.
If upper layer drivers are requesting to read non page aligned data NAND
subpage-read functionality reads the only whose ECC regions which include
requested data when original code reads whole page.
This significantly improves performance in many cases.
Here are some digits :
UBI volume mount time
No subpage reads: 5.75 seconds
Subpage read patch: 2.42 seconds
Open/stat time for files on JFFS2 volume:
No subpage read 0m 5.36s
Subpage read 0m 2.88s
