SDK8.1 and SDK 9.0 app_gpiote and nrf_drv_gpiote conflict

[Susheel Nuguru]

In SDK8.1 and SDK9.0 we have new driver nrf_drv_gpiote which has GPIOTE interrfupt handler in conflict with app_gpiote library. How to fix this

[Susheel Nuguru]

I have tried to merge the conflicted GPIOTE_IRQHandler and tested few use cases, they seems to work. Make sure that you do not use same pin in both app_gpiote library and nrf_drv_gpiote driver.

1. delete the GPIOTE_IRQHandler in app_gpiote.c file
2. replace the below code with GPIOTE_IRQHandler handler in nrf_drv_gpiote.c file
3. in app_gpiote.c file remote static keyword for m_enabled_users_mask, m_user_array_size,m_user_count, mp_users, sense_level_toggle and sense_level_disable

SDK_8.1

merge_gpiote_handler .c

SDK_9.0

sdk_9.0.merge_gpiote_handler.c

Diff for fix in SDK 9.0 from @pkarc: www.diffchecker.com/nub7badx

Once again, make sure that there are no pin conflicts between library and driver and this should work just fine.

NOTE: Tested only on Keil

@Aryan Did you test this on gcc? I had to do a lot more than this to get my application to build. For example, both nrf_drv_gpiote.c and app_gpiote.c depend on the gpiote_user_t typedef. It became a bit of a mess.
