Create two sysfs entries for exposing the MAC address
and count from the MAX10 BMC register space. The MAC
address is the first in a sequential block of MAC addresses
reserved for the FPGA card. The MAC count is the number
of MAC addresses in the reserved block.

Changelog v1 -> v2:
- Updated the documentation for the mac_address and mac_count
sysfs nodes to clearify their usage.
- Changed sysfs _show() functions to use sysfs_emit() instead
of sprintf.
