This patchset adds FPGA image reload support on Intel PAC N3000 Card.
Image reload means that a reload mechanism of an FPGA, BMC, or
firmware image from FLASH or EEPROM after flash or program the images
without power cycle the server.

This patchset introduces 2 new sysfs files for query the available
images and trigger a image reload.

patch 1: add register access helper functions for M10BMC.
patch 2: add the available_images and image_load sysfs files.
Write a key word into image_load sysfs file to trigger a reload of an
FPGA, BMC, or firmware image from FLASH or EEPROM.
patch 3: add a trigger to update a new Retimer firmware.

v2:
add more detail about how to use the image_load sysfs files in ABI
documentation.
