target/openrisc: Merge tlb allocation into CPUOpenRISCState
There is no reason to allocate this separately. This was probably copied from target/mips which makes the same mistake. While doing so, move tlb into the clear-on-reset range. While not all of the TLB bits are guaranteed zero on reset, all of the valid bits are cleared, and the rest of the bits are unspecified. Therefore clearing the whole of the TLB is correct.
