[PATCH resend] MTD: nandsim: allow changing some module parameters

[Artem Bityutskiy <Artem.Bityutskiy@nokia.com>]

Grant write permissions to some nandsim module parameters
to make it possible to change them runtime e.g., via sysfs:

echo 1 > /sys/module/nandsim/parameters/rptwear

There is no reason to have that file read-only. This patches
also changes the permissions from octal to S_* format.
