Instead of having OMAPDSS HDMI audio functionality depending on the
ASoC HDMI audio driver, use a new config option so that
potential users, including ASoC, may select if needed.

Fake VSYNC support is a hack and has some bugs in it. It isn't used by any user
of DSS. Remove Fake VSYNC support. For DSI command mode and RFBI panels, a user
of DSS should wait for the completion of a frame by using the panel driver's
sync op.

DSS driver has not been "experimental" for many years now, so perhaps
it's time to remove the text from Kconfig titles.

CONFIG_OMAP2_DSS_SLEEP_BEFORE_RESET is used to avoid an unclear bug at
DSS reset time. The pm runtime will handle reset in the future, and this
code has to be removed. Hopefully we won't see this error anymore.

By default, the DSI is not getting enabled for omap4.
OMAP2PLUS does not catch this issue since it has ARCH_OMAP3.

The issue is only seen when using defconfig with ARCH_OMAP4 only.

The clock sources for DISPC_FCLK and LCD1_CLK are now specified in the board file.
There is no need for the hack config "CONFIG_OMAP2_DSS_USE_DSI_PLL" anymore.
Introduce function dpi_use_dsi_pll() which checks for the clock sources to decide
whether DSI PLL is to be used or not.

There's a 20ms sleep after VENC reset. It's unknown what bug this
circumvents and on what platforms. Add a Kconfig option to disable the
sleep.

For some unknown reason we may get SYNC_LOST errors from the display
subsystem at initialization time if we don't sleep before resetting the
DSS. See the source (dss.c) for more comments.

However, 50ms is quite long time to sleep, and with some configurations
the SYNC_LOST may never happen, so this patch creates a Kconfig option
to disable the sleep.

The core files of DSS2. DSS2 commits are split a bit artificially to
make the individual commits smaller, and DSS2 doesn't compile properly
without the rest of the core commits. This shouldn't be a problem, as no
configuration uses DSS2 yet.
