Call to dev_dbg in dataflash_read() is located to early, before
command[] is initialize to correct values, so it end up printing
values from previous invocation. Move it such that it prints current
call's values.

In anticipation of supporting chips that need it, extend the size of
struct flash_info's 'jedec_id' field to make room 2 byte of extended
device information as well as add code to fetch this data during
jedec_probe().

"For" loop in jedec_probe can be simplified to not need counter
'i'. Convert the code and get rid of the variable.

Lion's share of calls to pr_debug in this driver follow the pattern of
pr_debug("%s <message>", dev_name(<dev>), <arguments>), which should
be semantically identical to dev_dbg(<dev>, "<message>", <arguments>),
so replace such occurencies to simplify the code.
Convert the small minority of pr_debug that do not follow pattern from
above to use dev_dbg as well, for the sake of consistency.
Convert similar patter of printk(KERN_ERR, "%s: ...", dev_name(...),
...) to use dev_err instead.
No functional change intended.

MTD internal API presently uses 32-bit values to represent device
size. This patch updates them to 64-bits but leaves the external API
unchanged.
In general, changing from 32-bit to 64-bit values cause little
or no changes to the majority of the code with the following
exceptions:
- printk message formats;
- division and modulus of 64-bit values (mtd_div_by_wb,
mtd_div_by_eb may be used in some of such cases).
Was tested on phyFLEX i.MX6.

A lot of files rely on include/driver.h including include/of.h (and
this including include/errno.h. include the files explicitly so we can
eventually get rid of including of.h from driver.h

Right now we do not support persistent names for mtd devices. The
base name can be passed to add_mtd_device, but this is always appended
with a dynamic number. With this patch add_mtd_device takes a device_id
argument which can be used to create a mtd device with an exact name.
