This commit adds support for the Core Divider clocks of the Armada
375. Compared to Armada 370 and XP the Core Divider clocks of the 375
cannot be gated: only their ratio can be changed. This is reflected by
the fact that the enable, disable and is_enabled clock operations are
not defined, and that the enable_bit_offset field is also undefined.
