Andrzej Kacprowski a3efabee58 accel/ivpu: Fix sporadic VPU boot failure
Wait for AON bit in HOST_SS_CPR_RST_CLR to return 0 before
starting VPUIP power up sequence, otherwise the VPU device
may sporadically fail to boot.

An error in power up sequence is propagated to the runtime
power management - the device will be in an error state
until the VPU driver is reloaded.
