#1646346 — [PATCH 12/13] clk: mvebu: add support for 1866MHz variants

The Linksys WRT3200ACM CPU is clocked at 1866MHz. Add 1866MHz to
the list of supported CPU frequencies.

Noticed by the following warning:
[    0.000000] Selected CPU frequency (16) unsupported

Are the L2 and DDR clocks using sensible values?

Hi Andrew

As you expected more changes are needed to fully support the new
CPU frequency. Will send out a V2 later.

Thanks for catching this.
Ralph
