Petro Karashchenko 41c95da594 register_driver: fix driver modes accross the code 
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

README
======

This README discusses issues unique to NuttX configurations for the
STMicro 32F3348DISCOVERY development board featuring the STM32F334C8
MCU. The STM32F334C8 is a 72MHz Cortex-M4 operation with 64kB Flash
memory and 16KB RAM. The board features:

  - On-board ST-LINK/V2 for programming and debugging,
  - High brightness LED dimming with buck converter
  - One buck/boost converter
  - Four user LEDs and two push-buttons,
  - Easy access to most MCU pins.

Refer to http://www.st.com/en/evaluation-tools/32f3348discovery.html for
further information about this board.

Configurations
==============

  nsh:
  ----

    Configures the NuttShell (nsh) located at apps/examples/nsh.

  powerled:
  ---------

    This is a configuration for onboard high brightness LED dimming.

  buckboost:
  ---------

    This configuration uses apps/examples/smps and onboard buck/boost converter.

    WARNING: current limit is not implemented!
