clocksource/drivers/fttmr010: Fix clk reference leak in error paths

fttmr010_common_init() obtains the PCLK reference with
of_clk_get_by_name() but never calls clk_put(). If clk_prepare_enable()
fails the reference is leaked directly, and every error path that jumps
to out_disable_clock only calls clk_disable_unprepare(), which releases
the prepare/enable state but not the reference obtained from
of_clk_get_by_name().

Add clk_put() to the clk_prepare_enable() failure path and to the
out_disable_clock label so the clock reference is no longer leaked. The
success path keeps PCLK enabled for the lifetime of the timer and is
left untouched.
