PM / devfreq: exynos-bus: Fix NULL pointer dereference
Fix exynos-bus NULL pointer dereference by correctly using the local
generated freq_table to output the debug values instead of using the
profile freq_table that is not used in the driver.

Tested-by: Marek Szyprowski <m.szyprowski@samsung.com>
Fixes: b5d281f6c16d ("PM / devfreq: Rework freq_table to be local to devfreq struct")
