PDSC: correct condition for BSP:Board Config component

[VladimirUmek]

• use condition "Ensemble CMSIS_Driver" for device level filtering
• add "Services:Secure Enclave:Initialization Helper" to select SE API functions
• simplify remaining "Board Config Ex" conditions (BSP:Board Config ensures correct filtering)

[VladimirUmek]

Component BSP:Board Config consists of files:

libs/board_config/board_config.c
libs/board_config/board_config.h

board_config.c requires:

• Device:Startup
• Device:SOC Peripherals:PINCONF
• Services:Secure Enclave:Initialization Helper

These components could be listed under condition, but to align with current conditions, "Ensemble CMSIS_Driver" is selected to ensure device level filtering and component Services:Secure Enclave:Initialization Helper is added to ensure Secure Enclave APIs are selected.

All other "Board Config Ex" conditions can then be simplified to just require BSP:Board Config since required filtering is already done by "BSP Board Config" condition.
