If a device does not have bad blocks loop over the eraseblocks

driver to erase blocks instead of pages to gain more speed during
erasing. Also the mtd_dataflash driver modifies the erase_info
struct which causes the outer loop in the core to never end.

Renaud, you recently sent a patch to fix erase on non uniform
flashes. This patch should fix this (by accident) aswell (or maybe
it causes other problems ;). Could you please test this one?
Thanks
Sascha
It does work.
If I define /dev/env0 to be 64KB i.e two sectors, then data in both
sector has been erased.

mtd_op_erase = 65536
cfi_erase: erase 0x00000000 (size 65536)
intel_flash_erase_one:sect = 0
intel_flash_erase_one:sect = 1
