Subject: [PATCH 3.18 27/52] clk: mvebu: armada-38x: add support for 1866MHz variants

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ralph Sennhauser <ralph.sennhauser@...il.com>

commit 9593f4f56cf5d1c443f66660a0c7f01de38f979d upstream.

The Linksys WRT3200ACM CPU is clocked at 1866MHz. Add 1866MHz to the
list of supported CPU frequencies. Also update multiplier and divisor
for the l2clk and ddrclk.

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