19693: sys/color: extend unittest and fix module r=maribu a=kfessel
### Contribution description
this extends the unittest for sys_color testing more colors
### Testing procedure
```
RIOT_tree/tests/unittests$ make tests-color test
```
will fail since our `rgb2hsv` implementation is wrong (or is using an other colorspace than hsv2rgb (without documenting))
the new `hsv2rgb` test will succeed
### Issues/PRs references
#19614 was the reason i had a look at this
#1315 added the rgb2hsv and hsv2rgb function
#9940 added the test for black special case
https://www.vagrearg.org/content/hsvrgb << some optimization for that function (avoiding float)

### Contribution description
This reverts #13462, this workaround is no longer needed with newer GCC version.
### Testing procedure
Try to compile tests/unittests for `saml11-xpro` or `saml10-xpro`

19618: cpu/stm32: fix riotboot settings for L4 and WB r=benpicco a=gschorcht
### Contribution description
This PR fixes the `riotboot` configuration for L4 and WB.
The family is not called `stm32l4` or `stm32wb` but `l4` and `wb`. That is, the `riotboot` configuration didn't work at all. Furthermore, a minimum `RIOTBOOT_LEN` of `0x2000` is required for L4.
Found when investigating the compilation errors for `bootloaders/riotboot_serial` in PR #19576.
### Testing procedure
1. Green CI.
2. Use the following commands:
```
BOARD=nucleo-l496zg make -C tests/riotboot info-debug-variable-RIOTBOOT_HDR_LEN
BOARD=p-nucleo-wb55 make -C tests/riotboot info-debug-variable-RIOTBOOT_HDR_LEN
```
In master these commands give
```
0x400
```
With this PR these commands give
```
0x200
```
as expected.
3. Use the following commands:
```
BOARD=nucleo-l496zg make -C tests/riotboot info-debug-variable-RIOTBOOT_LEN
BOARD=p-nucleo-wb55 make -C tests/riotboot info-debug-variable-RIOTBOOT_LEN
```
In master these commands give
```
0x1000
```
With this PR these commands give
```
0x2000
```
as expected.

19571: cpu/stm32/periph_adc: fixes and improvements for L4 support r=benpicco a=gschorcht
### Contribution description
This PR provides the following fixes and improvements for the `periph_adc` implementation for STM32L4.
- Support STM32L496AG added.
- Instead of defining the number of ADC devices for each MCU model, the number of ADC devices is determined from ADCx definitions in CMSIS header.
- MCU specific register/value defines are valid for all L4 MCUs, model based conditional compilation is removed.
- The ADC clock disable function is fixed using a counter. The counter is incremented in `prep` and decremented in `done`. The ADC clock is disabled if the counter becomes 0.
- For boards that have not connected the V_REF+ pin to an external reference voltage, the VREFBUF peripheral can be used as V_REF+ (if supported) by setting `VREFBUF_ENABLE=1`.
- The ASCR register is available and has to be set for all STM32L471xx, STM32L475xx, STM32L476xx, STM32L485xx and STM32L486xx MCUs. Instead of using the CPU model for conditional compilation, the CPU line is used to support all MCU of that lines.
- Setting of SQR1 is fixed. Setting the SQR1 did only work before because the `ADC_SRQ_L` is set to 0 for a sequence length of 1.
- Setting the `ADC_CCR_CKMODE` did only work for the reset state. It is now cleared before it is set. Instead of using the `ADC_CCR_CKMODE_x` bits to set the mode, the mode defines are used.
- Support for V_REFINT as ADC channel added.
