usb: dwc2: Fix shutdown callback in platform
commit 4fdf228cdf6925af45a2066d403821e0977bfddb upstream.
To avoid lot of interrupts from dwc2 core, which can be asserted in
specific conditions need to disable interrupts on HW level instead of
disable IRQs on Kernel level, because of IRQ can be shared between
drivers.
