### Contribution description
This PR provides the implementation of the LCD low-level MCU 8080 parallel interface using the FMC peripheral.
### Testing procedure
```

```
and
```
BOARD=stm32l496g-disco make -C tests/drivers/st77xx flash
```
should work on top of PR #19941. Drawing operations should be much faster.

Either the wiki is down, or the image was removed from upstream. This
replaces it with the same image hosted on the zephyr doc. As a site

### Contribution description
This PR fix some language issues in the output of `ifconfig set`.
### Testing procedure
Compile any program with `gnrc_netif` module, for example `examples/gcoap`.
Compare last line of presented outputs.
Output of `ifconfig help` without this PR.
```
All up, running the shell now

ifconfig help
usage: ifconfig help
usage: ifconfig <if_id> [up|down]
usage: ifconfig <if_id> set <key> <value>
Sets an hardware specific specific value

To support lwIP better (dont require gnrc_ipv6)
Also don't require IPv6 for printing link type
With this sc_gnrc_netif can compile and work when using lwIP
(with l2util module added):
```
> ifconfig
Iface ET1 HWaddr: 24:0A:C4:E6:0E:9C Channel: 6 Link: up
L2-PDU:1500 Source address length: 6
Link type: wireless
inet6 addr: fe80::260a:c4ff:fee6:e9c scope: link
inet6 addr: 2001:db8::260a:c4ff:fee6:e9c scope: global
Iface ET0 HWaddr: 24:0A:C4:E6:0E:9F Link: up

```
Still works in gnrc_networking example:
```

19954: sys/psa_crypto: Ed25519 (EdDSA) support r=miri64 a=mguetschow
### Contribution description
- implement [`psa_sign_message()`](https://armmbed.github.io/mbed-crypto/html/api/ops/sign.html#c.psa_sign_message) and [`psa_verify_message()`](https://armmbed.github.io/mbed-crypto/html/api/ops/sign.html#c.psa_verify_message) for the two already supported [`PSA_ALG_ECDSA`](https://armmbed.github.io/mbed-crypto/html/api/ops/sign.html#c.PSA_ALG_ECDSA) algorithms, together with the CryptoCell and `micro-ecc` backends (*not* for the SE backend)
- add support for [`PSA_ALG_PURE_EDDSA`](https://armmbed.github.io/mbed-crypto/html/api/ops/sign.html#c.PSA_ALG_PURE_EDDSA), together with the CryptoCell hardware and `c25519` software backend (*not* for the SE backend)
- wipe private key data from stack for both ECDSA and EdDSA algorithms using `explicit_bzero()` (opinions from experienced Riot maintainers about usage of `goto` to avoid duplicating that function call before every `return`?)
### Testing procedure
- `examples/psa_crypto` has been updated to include EdDSA
- successfully tested configurations:
- `nrf52840dk` with cryptocell (hardware) and `c25519` (software) backend
- `native` with software backend
### Issues/PRs references
Thanks `@Einhornhool` for the PSA Crypto framework implementation #18547 which is great to work with!

19941: drivers/lcd: add MCU-driven low-level parallel interface r=benpicco a=gschorcht
### Contribution description
The PR extends the LCD driver by a low-level interface for MCU-driven implementations of the MCU 8080 16-/8-bit parallel interface, allowing the MCU to use special peripherals for the interface, such as the FMC for STM32 MCUs, which is significantly faster than the integrated GPIO-driven parallel interface implementation of the LCD driver.
### Testing procedure
~Once PR #19938 and PR #19939 are merged, a PRs for these board can be pushed that allow to test this PR.~
Use either PR #19943 or PR #19944 on top of this PR to test, e.g. with PR #19943:
```
BOARD=stm32f723e-disco make -j8 -C tests/drivers/st77xx flash
```

19962: cpu/esp32: fix RISC-V ISA for ESP32-C3 with GCC 12.2 r=maribu a=gschorcht
### Contribution description
This PR fixes the RISC-V ISA spec in compiler and linker flags for ESP32-C3 and GCC 12.2.
Earlier versions of the specs and tools subsumed `zicsr` and `zifencei` into the `I` extension which is no longer the case. Therefore, the RISC-V ISA spec in compiler and linker flags had to be changed from `-march=rv32imc` to `-march=rv32imc_zicsr_zifencei`.
As a consequence floating-point arithmetics and I/O were no longer working with `-march=rv32imc` with GCC 12.2 since `riscv32-esp-elf/lib/libm_nano.a` was linked instead of `riscv32-esp-elf/lib/rv32imc_zicsr_zifencei/ilp32/libm_nano.a` because `riscv32-esp-elf/lib/rv32imc/ilp32/libm_nano.a` is not existing in the toolchain.
### Testing procedure
Add a
```c
#include <math.h>
...
printf("sin(x): %f\n", sin(1.0f));
```
in the `main` function of any application. Without this PR the application should crash while it should work with this PR.
