fs: add pread and pwrite functions
Add pread and pwrite functions.
Split read and write functions to save some space.
The functions pread and pwrite saves and sets the file
position to a given offset and restore them afterwards.
This also makes the nandtest command use these function
which is necessary to not break compilation for the nandtest
command.
