accel/ivpu/37xx: Fix hangs related to MMIO reset

There is no need to call MMIO reset using VPU_37XX_BUTTRESS_VPU_IP_RESET
register. IP will be reset by FLR or by entering d0i3. Also IP reset
during power_up is not needed as the VPU is already in reset.

Removing MMIO reset improves stability as it a partial device reset
that is not safe in some corner cases.

This change also brings back ivpu_boot_pwr_domain_disable() that
helps to properly power down VPU when it is hung by a buggy workload.
