Replace msleep by cond_resched. On machines with HZ=100 (e.g. ARM)
msleep slows down the operation by factor 10

This driver does not have as many options but it's easier to maintain.
And, it turns out AMD never shipped boards with different flash densities.

Check timeout while we wait for the command to finish. No worry about a
false result. This prevents deadlocking when detecting an unknown number
of chips and is useful for removable media too.

The change to the generic probe to look for the
smallest width of chip first is causing some problems
on boards with a single 16bit device.
The problem seems to be the jedec_match() is truncating
the device-id read from the table to match against the
one read from the hardware, causing a match against the
partial id of some chips with 16bit IDs (such as the
SST39LF160)
This fixes things for my own board, but something may
need to be done if the same problem is exhibited for
chips with an 8bit ID

When scanning NAND for bad blocks, don't read the whole page, read
only needed OOB bytes instead. Also check the return code of the
nand_read_raw() function. Correctly free the this->bbt array in
case of failure. Tested with Large page NAND.
Fix debugging message.

This is implemented using a ioctl to switch the MTD char device into
one of the different OTP "modes", at which point read/write/seek can
operate on the selected OTP area. Also some extra ioctls to query
for size and lock protection segments or groups. Some example user
space utilities are provided.

This enables support for reading, writing and locking so called
"Protection Registers" present on some flash chips.
A subset of them are pre-programmed at the factory with a
unique set of values. The rest is user-programmable.
