- Change “" by”/" in the include path to fix compilation issue under Linux
Miscellaneous comments update

stm324xg_eval_audio.c/.h
- BSP_AUDIO_OUT_Play(): uses the buffer size in byte instead of half-word

stm324xg_eval.c/.h
- Add protection for double initialization of IO_Init within LCD_IO_Init()
- Enhance BSP_PB_Init() function by removing the call of __SYSCFG_CLK_ENABLE() already enabled in the HAL_GPIO_Init()
stm324xg_eval_audio.c/.h
- Add note that only the audio stereo format is supported
stm324xg_eval_sd.c/.h
- Ensure compatibility with the updated version of FatFs sd_diskio driver (i.e. FatFs R0.10 ST modified 20140422) supporting SDIO/SPI to interface uSD
- Comments clean up and typo corrections

stm324xg_eval_sd.c/.h
- Update SD_DATATIMEOUT value
stm324xg_eval_eeprom.c/.h
- Update usage of BSP_EEPROM_TIMEOUT_UserCallback() function

Major update based on STM32Cube specification: drivers architecture and APIs modified vs. V1.1.1, and thus the 2 versions are not compatible.
This version has to be used only with STM32CubeF4 based development

stm324xg_eval_ioe.c
- Update the MEMS pins configuration in IOE_Config() function.
- Update I2C communication sequence in I2C_ReadDataBuffer() function to ensure efficient and robust I2C transfer.
stm324xg_eval_lcd.c
- Replace STM324xG_LCD_Init() function by LCD_Init() function and add a legacy for old LCD Initialization function name for compatibility purpose.

stm3224xg_eval_sdio_sd.h/.c
- Support SDHC memory cards with capacity greater than 4 GB
- Transmit and receive functions: swap the order of state machine and DMA configuration, to fix marginal limitation where the card sent data to the SDIO interface while the DMA is not ready to transfer them
- Support SDHS (High Speed) memory cards, add new function SD_HighSpeed()
stm324xg_eval_ioe.c
- Configuration clean up and corrections
- Touch screen (TSC) Interrupt mode enhancement
- Update Read/Write low layer functions to ensure efficient and robust I2C transfer
  - Update legacy functions I2C_WriteDeviceRegister(), I2C_ReadDeviceRegister() and I2C_ReadDataBuffer() to use polling mode instead of DMA
  - Add three new functions I2C_DMA_WriteDeviceRegister(), I2C_DMA_ReadDeviceRegister() and I2C_DMA_ReadDataBuffer(), for DMA based I2C transfer
stm324xg_eval.c
- SD_LowLevel_Init(): Set the GPIO clock to 50MHz to support High Speed mode
stm324xg_eval_i2c_ee.c
- Enable I2C DMA request only after the enable of the DMA stream, to avoid DMA FIFO error generation
stm324xg_eval_fsmc_sram.c
- Change memory type to SRAM instead of PSRAM (PSRAM is available only on STM324xG-EVAL RevA) and update timing values

All source files: license disclaimer text update and add link to the License file on ST Internet.
stm324xg_eval_lcd.c
- Enhance Gamma Curve settings for ILI9320 controller
stm324xg_eval.c and stm324xg_eval_ioe.c
- Swap the order of I2C IOs and alternate function (AF) configuration: AF configuration should be done before to configure the IOs.
stm324xg_eval_sdio_sd.c
- In SD_WaitWriteOperation() and SD_WaitReadOperation() functions: reset StopCondition flag after sending CMD12

All source files: update disclaimer to add reference to the new license agreement
stm324xg_eval_lcd.c
- Remove “static” from TextColor and BackColor variables declaration (need to be changed from other application modules)
stm324xg_eval_ioe.h
- Add conditional compilation on the default DMA stream(s) used for I2C1 Tx and Rx transfers, to allow user to change them from application level.
stm322xg_eval_sdio_sd.h
- SD_CardInfo structure, define CardCapacity variable as 64-bit long (instead of 32-bit) to support SDHC memory cards with capacity greater than 4 GB.
stm324xg_eval_fsmc_sram.c
- Add IOs config of missing FSMC address lines (FSMC_A21, FSMC_A22 and FSMC_A23).

First official release for STM3240_41_G_EVAL board RevB drivers
stm322xg_eval_lcd.c: increase FSMC AddressSetupTime value from 4 to 5 to be compliant with some LCD access timing
