Damien George 3ef911345c stmhal: Update STM32Cube F4 HAL driver to V1.3.0. 
This patch updates ST's HAL to the latest version, V1.3.0, dated 19 June
2014.  Files were copied verbatim from the ST package.  Only change was
to suppress compiler warning of unused variables in 4 places.

A lot of the changes from ST are cosmetic: comments and white space.
Some small code changes here and there, and addition of F411 header.

Main code change is how SysTick interrupt is set: it now has a
configuration variable to set the priority, so we no longer need to work
around this (originall in system_stm32f4xx.c).

* @version V1.1.0
* @date 19-June-2014
* @brief HCD HAL module driver.
* This file provides firmware functions to manage the following
* functionalities of the USB Peripheral Controller:
* + Initialization and de-initialization functions
* + IO operation functions
* + Peripheral Control functions
* + Peripheral State functions

==============================================================================
##### How to use this driver #####
==============================================================================
[..]
(#)Declare a HCD_HandleTypeDef handle structure, for example:
HCD_HandleTypeDef hhcd;
(#)Fill parameters of Init structure in HCD handle
(#)Call HAL_HCD_Init() API to initialize the HCD peripheral (Core, Host core, ...)
(#)Initialize the HCD low level resources through the HAL_HCD_MspInit() API:
(##) Enable the HCD/USB Low Level interface clock using the following macros
(+++) __OTGFS-OTG_CLK_ENABLE() or __OTGHS-OTG_CLK_ENABLE()
(+++) __OTGHSULPI_CLK_ENABLE() For High Speed Mode
(##) Initialize the related GPIO clocks
(##) Configure HCD pin-out
(##) Configure HCD NVIC interrupt
(#)Associate the Upper USB Host stack to the HAL HCD Driver:
(##) hhcd.pData = phost;
(#)Enable HCD transmission and reception:
(##) HAL_HCD_Start();
