[riot-notifications] [RIOT-OS/RIOT] cpu/lpc2387: Cleanup (#11920)

Note: The boot up sequence of the LPC2387 is quite weird, with clock setup in the `boards/` rather than in `cpu/`. I intend to clean this up with a series of PRs. A side effect from the code organization is that this PR touches files in seemingly unrelated subsystems...

### Contribution description
- Removed unused and defunct code from the clock configuration during boot up
- Removed obsolete ISR implementations that are not registered anywhere anymore and thus never get triggered
- Removed function declarations of functions that are neither used nor implemented anywhere
- Previously boot up code and ISR implementations where mixed together in `bootloader.c`
    - Moved ISR implementations to `vector.c` and applied naming scheme used by other modules in `cpu/`
    - Moved boot up code to `arm7_init.c`.

### Testing procedure
Try to build, flash, and run some applications and tests currently working on the MSB-A2. They should still work
