regulator: max8660: fix assignment of pdata to data that becomes dead
pdata is assigned to &pdata_of, however, pdata_of becomes dead (when it
goes out of scope) so pdata effectively becomes a dead pointer to the
out of scope object. This is detected by static analysis:
[drivers/regulator/max8660.c:411]: (error) Dead pointer usage.
Pointer 'pdata' is dead if it has been assigned '&pdata_of' at line 404.
Move declaration of pdata_of so it is always in scope.
