hw/block/nvme: add support for the get log page command
Add support for the Get Log Page command and basic implementations of
the mandatory Error Information, SMART / Health Information and Firmware
Slot Information log pages.
In violation of the specification, the SMART / Health Information log
page does not persist information over the lifetime of the controller
because the device has no place to store such persistent state.
Note that the LPA field in the Identify Controller data structure
intentionally has bit 0 cleared because there is no namespace specific
information in the SMART / Health information log page.
Required for compliance with NVMe revision 1.3d. See NVM Express 1.3d,
Section 5.14 ("Get Log Page command").
