Carles Cufi 8c748fd005 kernel: Modify the signature of k_mem_slab_free()
Modify the signature of the k_mem_slab_free() function with a new one,
replacing the old void **mem with void *mem as a parameter.

The following function:
void k_mem_slab_free(struct k_mem_slab *slab, void **mem);

has the wrong signature. mem is only used as a regular pointer, so there
is no need to use a double-pointer. The correct signature should be:
void k_mem_slab_free(struct k_mem_slab *slab, void *mem);

The issue with the current signature, although functional, is that it is
extremely confusing. I myself, a veteran Zephyr developer, was confused
by this parameter when looking at it recently.

All in-tree uses of the function have been adapted.

Fixes #61888.

Jonathan Rico f8e5e17246 drivers: led_strip: add WS2812 I2S-based driver
Add a driver implementation that uses the I2S peripheral.
Based off this blog post:
https://electronut.in/nrf52-i2s-ws2812/

Should help with #33505, #29877 and maybe #47780, as there is no garbage
data at the end of transmissions on nRF52832, and no gaps.
