Could you adding a space between "&" and "0xff" during this fix?
ih_rb_cntl = REG_SET_FIELD(ih_rb_cntl, IH_RB_CNTL, MC_SPACE, 1);
} else {
WREG32(SOC15_REG_OFFSET(OSSSYS, 0, mmIH_RB_BASE),

Maybe miss the "else" case, like below:
WREG32(SOC15_REG_OFFSET(OSSSYS, 0, mmIH_RB_BASE_HI), (adev->irq.ih.gpu_addr
>> 40) & 0xff);
