1、feat add link-bootloader.lds[start from 0x60000000] and link-application.lds[start from 0x60040000];

2、support BSP_USING_OTA MCUBOOT_BOOTLOADER and MCUBOOT_APPLICATION in xidatong-arm32/Kconfig;
3、support compile XiZi-xidatong-arm32-boot.bin when enable MCUBOOT_BOOTLOADER and XiZi-xidatong-arm32-app.bin when enable MCUBOOT_APPLICATION;
4、add QSPIFlash function for xidatong-arm32。
