mtd: nand: do not write empty pages
Do not write pages which only contain 0xff. UBI expects pages which
seem empty to be writable. This got lost with:

| mtd core: call driver write function with complete buffer
|
| mtd->write is supposed to loop around pages internally, no need
| to do this in mtd_write. This fixes a huge write performance drop
| with the m25p80 driver when it was converted to a mtd driver recently.
| Since mtd->writesize is 1 for this driver mtd_write ended up doing
| single byte writes on the flash.
Introduce mtd_all_ff as a global function since UBI currently has its own
implementation.
