[PATCH] clk: si5351: Allow to build without CONFIG_OF

[Sebastian Hesselbarth]

In clk-si5351 there was some dependency to CONFIG_OF that permitted the
use of the driver on !CONFIG_OF platforms. This patch adds proper #ifdef
around of_clk_add_provider and removes the dependency on CONFIG_OF.

Note:
This patch is based upon v3.9-rc8 with clk-si5351 v8 plus two fixes by
Marek Belisko applied. It has been compile-tested on x86_64 allmodconfig.
