Fix vector table relocation for NRF52
The vector table relocation sequence depends on: 1. Whether the SoftDevice is present. 2. The Application is a bootloader or not. If the SoftDevice is present and the application is a bootloader the MBR must be initialized to trap SoftDevice service calls before setting the new vector table address. The SCB->VTOR must be set to point at the MBR as well. If the SoftDevice is not present the SCB->VTOR can point at the new vector table directly.pull/6746/head
