Hello,

v3:
1. Update the PowerNV maintainer section to include hw/ssi/pnv_spi*
2. Use of PnvXferBuffer results in a additonal process overhead due to
frequent dynamic allocations and hence use an existing Fifo8 buffer.
3. Use a local variable seq_index and use it with in while loop instead
of repeatedly calling get_seq_index() and make sure s->seq_op doesn't
overrun when seq_index is incremented.

Tested:
passed make check and make check-avocado
