[Silabs] Fixed the 917 NCP init (#37147)

* Added fix for ncp init issue

* Removed commented code

* Removed unused variables

* Resolved review comments

* Reverted sl_board_configuration.h header include

* Resolved review comments

* Added latest sdk_support pointer and resolved review comments

* Added comment for SPI transfer API

* Disabled lcd and external flash in silabs_boards.gni for 917 NCP board

* Added TODO for removing disabling lcd and enable external flash

* TODO added properly in silabs_board.gni file
