POWER8 allows us to take interrupts with the MMU on. This gives us a second set of vectors offset at 0x4000. Unfortunately when coping these vectors we missed checking for MSR HV for hardware interrupts (0x500). This results in us trying to use HSRR0/1 when HV=0, rather than SRR0/1 on HW IRQs The below fixes this to check CPU_FTR_HVMODE when patching the code at 0x4500. Also we remove the check for CPU_FTR_ARCH_206 since relocation on IRQs are only available in arch 2.07 and beyond. Thanks to benh for helping find this.
