mtd: nand: drop unnecessary partition parser data
All of these drivers set up a parser data struct just to communicate DT
partition data. This field has been deprecated and is instead supported
by telling nand_scan_ident() about the 'flash_node'.
This patch:
* sets chip->flash_node for those drivers that didn't already (but used
OF partitioning)
* drops the parser data
* switches to the simpler mtd_device_register() where possible, now
that we've eliminated one of the auxiliary parameters
Now that we've assigned chip->flash_node for these drivers, we can
probably rely on nand_dt_init() to do more of the DT parsing for us, but
for now, I don't want to fiddle with each of these drivers. The parsing
is done in duplicate for now on some drivers. I don't think this should
break things. (Famous last words.)
