pflash: fix erase command when using mtd backend
The libflash mtd backend lacked support for full-chip erase so it did
not work. This patch adds that support to libflash. Patch is on it's
way upstream[1].
Note: the old MMIO access method could perform a wole-chip
erase on SPI NOR parts that supported it. This was sometimes a fraction
faster than erasing each page one-by-one when re-flashing the entire
chip.
The mtd API does not (yet) provide a userspace API for that, so libflash
always erases the flash one page at a time. This means you are better
off using the -e command over -E.
