Subject: [PATCH 5.15 036/107] musb: fix USB_MUSB_TUSB6010 dependency

From: Arnd Bergmann <arnd@...db.de>

commit a3f2fd22743fc56dd5e3896a3fbddd276df1577f upstream.

Turning on NOP_USB_XCEIV as builtin broke the TUSB6010 driver because
of an older issue with the depencency.

It is not necessary to forbid NOP_USB_XCEIV=y in combination with
USB_MUSB_HDRC=m, but only the reverse, which causes the link failure
from the original Kconfig change.

Use the correct dependency to still allow NOP_USB_XCEIV=n or
NOP_USB_XCEIV=y but forbid NOP_USB_XCEIV=m when USB_MUSB_HDRC=m
to fix the multi_v7_defconfig for tusb.

Fixes: ab37a7a890c1 ("ARM: multi_v7_defconfig: Make NOP_USB_XCEIV driver built-in")
Fixes: c0442479652b ("usb: musb: Fix randconfig build issues for Kconfig options")
