register_driver: fix driver modes accross the code

Browse Source 
State of problem:
 - Some drivers that do not support write operations (does not
   have write handler or ioctl do not perform any write actions)
   are registered with write permissions
 - Some drivers that do not support read operation (does not
   have read handler or ioctl do not perform any read actions)
   are registered with read permissions
 - Some drivers are registered with execute permissions

Solution:
 - Iterate code where register_driver() is used and change 'mode'
   parameter to reflect the actual read/write operations executed
   by a driver
 - Remove execute permissions from 'mode' parameter
