Add boot count into motherboard eeprom and clear command
The bmc boot count which was previously stored into
the file /etc/conf/bios.cnt, is now stored into the
motherboard FRU eeprom/sys/bus/i2c/devices/4-0050/eeprom
starting from offset of 4 bytes from 0x1000.
The reading and writing to the FRU eeprom is handled
by using the helper functions.
Added the new IPMI clear command which sets the eeprom
to the default value of ff ff ff ff.
Use of 4 bytes from 0x1000 location to check
if the boot counter is at the max value or at the default
value which server as a header to the boot count.
All corner cases such as invalid command and invalid
command length have been added
Tested:
ipmitool raw 0x34 0x71 0x00 - read current boot count.
ipmitool raw 0x34 0x71 0x01 - increment the boot count by 1.
ipmitool raw 0x34 0x71 0x02 - set the boot_count to all ff which
is its default value of eeprom location where the boot count is
stored.
ipmitool raw 0x34 0x71 0x03 byte1 byte2 byte3 byte4 - set the
boot count to desired value provided by the request parameter.
Reboot,powercyle,flashing bmc - performed to see if the value
retains.
