EMW3165 platform.c is missing WWD_PIN_32K_CLK in wifi_control_pins #21

GPIO pin for WWD_PIN_32K_CLK is not defined in EMW3165 platform.c. However, WICED_USE_WIFI_32K_CLOCK_MCO is defined in platform_config.h, which causes code in STM32F4xx/WWD/wwd_platform.c:host_platform_init_wlan_powersave_clock() to attempt setup with undefined values.

This causes problems if one wants to use MCU powersaving features as 32 Khz clock is not delivered to Wifi chip as expected.

I couldn't find any schematic which would tell to which STM32 pin is used for clock inside module :-(

MCU powersave works with two changes in platform_config.h:

comment out WICED_USE_WIFI_32K_CLOCK_MCO
change WICED_WIFI_OOB_IRQ_GPIO_PIN to 1 (otherwise there is no OOB interrupt).
