mtd: nand: Remove docg4 driver and palmtreo680 flashing tool

Commit ad4f54ea86b ("arm: Remove palmtreo680 board") removed the only
user of the docg4 driver and the palmtreo680 image flashing tool.  This
patch removes them.

- * This is a userspace Linux utility that, when run on the Treo 680, will
- * program u-boot to flash.  The docg4 driver *must* be loaded with the
- * reliable_mode and ignore_badblocks parameters enabled:
- *
- *        modprobe docg4 ignore_badblocks=1 reliable_mode=1
- *
- * This utility writes the concatenated spl + u-boot image to the start of the
- * mtd device in the format expected by the IPL/SPL.  The image file and mtd
- * device node are passed to the utility as arguments.  The blocks must have
- * been erased beforehand.
- *
- * When you compile this, note that it links to libmtd from mtd-utils, so ensure
- * that your include and lib paths include this.
