[POWERPC] Fix bugs in the hypervisor call stats code
There were a few issues with the HCALL_STATS code: - PURR cpu feature checks were backwards - We iterated one entry off the end of the hcall_stats array - Remove dead update_hcall_stats() function prototype I noticed one thing while debugging, and that is we call H_ENTER (to set up the MMU hashtable in early init) before we have done the cpu fixups. This means we will execute the PURR SPR reads even on a CPU that isnt capable of it. I wonder if we can move the CPU feature fixups earlier.
