hw/ipmi: Disable flash access when requested
BMC based systems contain a PNOR to provide flash storage. The host
normally has exclusive access to the PNOR, however the BMC may use IPMI
to request access to perform functions such as update the firmware.
Indicate to users of the flash that the device is busy by taking the
lock, and setting a per-flash busy flag, which causes flash operations
to return OPAL_BUSY.
