[PATCH v9 3/9] thermal/drivers/exynos: Handle optional triminfo clock correctly

[Anand Moon]

The triminfo clock is obtained using devm_clk_get_optional_prepared(),
which returns NULL when the optional clock is not present.

Update the clock checks in exynos_tmu_initialize() to test for NULL
instead of using IS_ERR(), allowing TMU instances without a triminfo
clock to initialize correctly.
