kernel: yaffs: use new_sync_{read,write} for 3.18+
...
Using the do_sync_{read,write} functions in conjunction
with the generic_file_{read,write}_iter causes a kernel
panic like this:

Change the yaffs code to use the new_sync_{read,write} functions
instead.

kernel: bump to 3.14.35, 3.18.9, 3.19.1 and 4.0-rc4
...
also refresh generic patches for 3.14, 3.18, 3.19 and 4.0
targets might need a minor refresh as well, however, it looks
like everything still applies cleanly with occasional small
offsets.
