cxl: Read vsec perst load image
This bit is used to cause a flash image load for programmable CAIA-compliant implementation. If this bit is set to ‘0’, a power cycle of the adapter is required to load a programmable CAIA-com- pliant implementation from flash. This field will be used by the following patches.
