ARM: OMAP2+: hwmod code: convert missing clockdomain warnings to debug messages
The decision was made a few months ago to allow struct omap_hwmod
records and struct clk records to omit clockdomain information if the
clockdomain is not software-controllable. See for example commit
868c157df9721675c19729eed2c96bac6c3f1d01 ("ARM: OMAP2+: hwmod: remove
prm_clkdm, cm_clkdm; allow hwmods to have no clockdomain").
So convert an existing pr_warning() to a pr_debug() (regarding missing
clockdomains in clocks), and add a pr_debug() for missing hwmod
clockdomains. It's still useful to enable these messages for
debugging, since missing clockdomains can cause hard-to-debug problems
with power management; see for example commit
6c4a057bffe9823221eab547e11fac181dc18a2b ("ARM: OMAP4: clock data:
Force a DPLL clkdm/pwrdm ON before a relock").
