[PATCH v9 5/7] clk: rockchip: fix error for unknown clocks

[Sebastian Reichel <sebastian.reichel@collabora.com>]

There is a clk == NULL check after the switch to check for
unsupported clk types. Since clk is re-assigned in a loop,
this check is useless right now for anything but the first
round. Let's fix this up by assigning clk = NULL in the
loop before the switch statement.
