To obtain coordinates from the touch panel that correspond to the display coordinates, it is often necessary to convert the coordinates from the touch display by swapping and mirroring. For the sake of simplicity, possible rotations are additionally defined.

19733: cpu/msp430: reorganize code r=maribu a=maribu
### Contribution description
RIOT supports two distinct families of the MSP430: The [MSP430 x1xx] MCU family and the [MSP430 F2xx/G2xx] MCU family. For both incompatible MCU families the code was located in the msp430fxyz folder, resulting in case of the UART driver in particularly bizarre code looking roughly like this:
```C
#ifndef UART_USE_USCI
/* implementation of x1xx peripheral ... */
#else
/* implementation of F2xx/G2xx peripheral ... */
#endif
/* zero shared code between both variants */
```
This moves peripheral drivers shared between the two families to msp430_common and splits the SPI and UART driver into two MCU families.
In addition, it cleans up the `msp430_regs.h` by dropping most of it and using the macros and symbols provided by the vendor header files. There is little reason for us to maintain constants when TI is already doing that.

19769: cpu/nrf53: add initial support with nRF5340DK-APP board r=maribu a=dylad
### Contribution description
This PR adds support for nRF5340 MCU and its associated Nordic development board, nRF5340DK.
This MCU provides a dual Cortex-M33, one application core running at up to 128MHz, and one network core running at up to 64MHz.
Peripherals are inherited from others Nordic MCUs families so it shouldn't be hard to add more of them in followup PRs.
For now, only the minimal set of peripherals is supported:
- GPIO / GPIO_IRQ
- UART
- TIMER
### Testing procedure
Build the usual test application for the supported peripherals and flash the board.
nRF5340DK provides two serial ports on its embedded debugger. RIOT's shell should be available on the first one (/dev/ttyACM0)

The MSP430 vendor files already provide macros containing register
constants and symbols (provided via linker scripts) containing addresses
of peripheral registers. So lets make use of that rather than
maintaining a long list of constants.
Provide a common clock initialization driver rather than leaving
clock initialization to the boards code. A declarative description of
the board's clock configuration using a struct does still allow to
fine-tune settings. In addition, a board is still allowed to just
provide a custom `void clock_init(void)` if there really is the need
to do crazy things.
