8951711f96 drivers: uhc: udc: use DYNAMIC_INTERRUPTS for KHCI and EHCI
Because the same IP supports both device and host, so use
DYNAMIC_INTERRUPTS for KHCI and EHCI if both device and host
are enabled.

fa7752494d usb: host: rework usbh_xfer_alloc() parameters
The transfers require enpoint MPS for proper transaction handling,
assign it in the common place during transfer allsocation so that it can
be reused.
Some users, such as USBIP, may need to keep a reference to private data,
add a parameter for completion callback data.

Add an opaque pointer to store upper layer private data and initialize
it with the USB host context during controller initialization. Use the

a7c8a8d46d drivers: uhc: remove UHC transfer parameter addr and attrib
Address parameter/argument is no longer needed because we have a pointer
to the USB device. The Attrib parameter has never been used and will be
replaced by the interval and start-frame parameters in the future.

7f53eca7c5 drivers: uhc_virtual: allow multiple transfers scheduled within a frame
With the current implementation, NACK claims all resources and prevents
scheduling multiple transfers within a frame. Place a number of
available transfers in a list at the beginning of a frame, and process
the transfers in a limited number of slots.

9cb777b95e drivers: uhc: rework transfer buffer handling
The current approach is a bit impractical in the upper layer.
This patch removes the two fifos that hold the transfer buffers
and replaces them with a byte array for the setup packet and
a pointer to a data buffer. The data buffer is mandatory for
all types of transfers except control without a data stage.
The waste of eight unused bytes for non-control transfers should
be insignificant, since an additional pointer would be at least
half of it, and then there would be the overhead of handling it.

This patch also clean up the transfer flags, rename owner to callback
as it reflects the upper layer use case, and add an additional member
to hold the pointer to the USB device (peripheral on the bus).

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.

With gcc from the zephyr sdk and -Wold-style-declaration is giving this
output:

c41dd36de2 drivers: kconfig: unify menuconfig title strings
Unify the drivers/*/Kconfig menuconfig title strings to the format
"<class> [(acronym)] [bus] drivers".

Including both the full name of the driver class and an acronym makes
menuconfig more user friendly as some of the acronyms are less well-known
than others. It also improves Kconfig search, both via menuconfig and via
the generated Kconfig documentation.
