mtd: dataflash: Replace pr_debug, printk with dev_* functions

Browse Source 
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.
