From: Zoltán Böszörményi
My 2TB SKC2000 showed the exact same symptoms that were provided
in 538e4a8c57 ("nvme-pci: avoid the deepest sleep state on
Kingston A2000 SSDs"), i.e. a complete NVME lockup that needed
cold boot to get it back.
According to some sources, the A2000 is simply
the new
release_declared_region() macro.

This patch uses the previously introduced macro called
request_declared_muxed_region() to synchronize access to
the I/O port pair 0xcd6 / 0xcd7 on SB800.
These I/O ports are also used by i2c-piix4 and sp5100_tco,
the next two patches port these drivers to use the new macro.
