`device_next/usbd_ch9.c` depends on `CONFIG_HWINFO=y`, but `CONFIG_HWINFO` is only implied by `CONFIG_USB_DEVICE_STACK_NEXT`

[fkokosinski]

Describe the bug

As in the title - the user can n-select CONFIG_HWINFO, because it is only implied by CONFIG_USB_DEVICE_STACK_NEXT. The change from select to imply happened in: 9b87964.

Regression

• This is a regression.

Steps to reproduce

To reproduce, use the following commands:

1. west build -p -b stm32f429i_disc1/stm32f429xx samples/subsys/usb/shell -- -DCONFIG_HWINFO=n
2. See output
