On Lemote 2F CS5536 MSRs are accessed through a index / data register pair.
The access sequence must be protected by a spinlock to be atomic.
Without this rebooting in fs2f_reboot() may fail.

PCI support for the Fuloong 2E and Lemote Loongson 2F family machines is
mostly identical with the exception of CS5536 support.
Rename ops-fuloong2e.c to ops-loongson2.c then add the CS5536 support to
share most of the source code among Loongson machines.
