drivers: rework usb_dc_mcux_ehci

[jfischer-no]

This is bug fix, rework, and style fix of usb_dc_mcux_ehci

Fixes #19763

[jfischer-no]

Tested on IMXRT1050-EVKB, passes USB 2 CV Chapter 9 and all testusb tests now.

We should perhaps hold this back, merge it after 2.1 release, we are in -rc3 already.

@MarkWangChinese please review

[jfischer-no]

Rebased.

@MaureenHelm The header file modules/hal/nxp/mcux/middleware/usb/device/port/zephyr/usb_dc_mcux.h is a part of the driver. It hides a lot of things, has unnecessary complexity, and does not help to maintain the driver. This file should be moved to drivers/usb/device/usb_dc_mcux_hal.h and reworked/simplified. I would like to do that, this would also help to fix high speed support what I really would like to improve and test with imxrt1050.

@MaureenHelm did you still want someone else to review this? I see you mentioned @MarkWangChinese back in December.

[jhedberg]

@jfischer-phytec-iot there seems to be a conflict with drivers/usb/device/usb_dc_mcux_ehci.c so you'll need to rebase. @MaureenHelm is someone else still expected to review this?

@MaureenHelm this fixes a bug, has been opened for a while and is scheduled for this release. Could you review it so we can include it in the release?
