Subject: [PATCH 32/71] clk: remove log_ret from clk_get_rate

The return value of clk_get_rate is ulong, an unsigned type. The size of
ulong depends on the cpu architecture, i.e. 4 bytes on 32-bit CPUs and
8 bytes on 64-bit CPUs.

However log_ret only accepts and returns value in int type, a fixed 4-byte
type. This may truncate the real clock value and cause unexpected error on
64-bit platforms.

This patch removes log_ret to solve this issue.
