Don't assume eraseblock size is power of 2.
Dataflash can have aligned eraseblock size.

The changes introduced allow to suspend/resume NAND flash.
A new state (FL_PM_SUSPENDED) is introduced, as well as
routines for mtd->suspend and mtd->resume to put the flash in
suspended state from software pov.

- Intel chip driver has a reboot notifier so no need to reset the chip here.
- Don't play with chip selects (platform code should do this if necessary).

The bit mask used for oob size calculation was using 2 bits instead
of one. Fortunately the next bit has been 0 all the time.
Thanks to Nathan H. for pointing this out

While this might be useful for all supported flash types, it is mandatory
for proper JFFS2 support with Sibley flash.

This updates the Primary Vendor-Specific Extended Query parsing to
version 1.4 in order to get the information about the Configurable
Programming Mode regions implemented in the Sibley flash, as well as
selecting the appropriate write command code.
This flash does not behave like traditional NOR flash when writing data.
While mtdblock should just work, further changes are needed for JFFS2 use.
