USE_PM_CLK_RUNTIME_OPS is introduced so we don't repeat the same code
to do runtime_suspend and runtime_resume across users of PM clocks.
Use it to remove the boilerplate code.

After commit b2b49ccb (PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is
selected) PM_RUNTIME is always set if PM is set, so #ifdef blocks
depending on CONFIG_PM_RUNTIME may now be changed to depend on
CONFIG_PM.

Replace CONFIG_PM_RUNTIME with CONFIG_PM everywhere in the code under
arch/arm/ (the defconfig files will be modified later).

By default the VPSS clocks were enabled in capture driver
for davinci family which creates duplicates for dm355/dm365/dm644x.
This patch adds support to enable the VPSS clocks in VPSS driver,
which avoids duplication of code and also adding clock aliases.
This patch uses PM runtime API to enable/disable clock, instead
of DaVinci clock framework. con_ids for master and slave clocks of
vpss is added in pm_domain.
This patch cleanups the VPSS clock enabling in the capture driver,
and also removes the clock alias in machine file. Along side adds
a vpss slave clock for DM365 as mentioned by Sekhar
(https://patchwork.kernel.org/patch/1221261/).
The Suspend/Resume in dm644x_ccdc.c which enabled/disabled the VPSS clock
is now implemented as part of the VPSS driver.

do clk_get on connection id "fck" to support OMAP based
platforms having multiple clocks for module. Without this
driver change clk_get fails on am335x.

Add runtime PM core support to davinci by using the pm_clk
infrastructure of the PM core.

When runtime PM is enabled, the davinci runtime PM implementation will
use the pm_clk layer to enable/disable clocks on demand.  When runtime
PM is disabled, the pm_clk core will automatically enable clocks when
the driver is bound and disable clocks when the driver is unbound.
