msm: clock: Remove warned flag

Now that all clock consumers have moved over to using the
clk_prepare/unprepare APIs we can remove the warned flag that
used to indicate that we had already warned about improper usage
of the clock APIs. In particular, we used this flag to avoid
printing warnings for "source" clocks such as PLLs and
crystals that no consumer directly controls but that the clock
driver calls clk_enable() on during clk_set_rate().

Let's use a local variable for clk->dbg_name too because we use
it many times and it makes lines too long.

msm: msm_xo: Migrate to new clock APIs

Use the clk_prepare and clk_unprepare APIs to conform with the
changes to the clock APIs.

video: ensure esc_byte_ratio is set before controlling clocks

This was a diff from the correct CAF code and causes us to set
the clock divider incorrectly during the splash screen handoff.
