Originally DSS only had DSI PLLs, and thus the DPI driver has functions
and variables that refer to DSI or DSI PLL. Now we support DSI, VIDEO
and HDMI PLLs, so it's time to remove the DSI references from the code.

Type A and B PLLs require a bit different calculations for the clock
rates. DPI driver supports only type A PLLs.
This patch adds support for the type B PLL.
Type B PLLs are simpler than type A, as type B can produce a good clock
for almost any rate. Thus we can just ask it to produce the pixel clock
and use one as LCK and PCK dividers.

Add a "_a" postfix to the type A PLL calc functions, to differentiate
them from the type B PLL calculations which we will add shortly.

DPI driver uses a fixed clkout index, 0. This has worked fine as the
first clkout is usually used.
To generalize the code and to support additional clock sources, change
the code to use dss_pll_get_clkout_idx_for_src() to get the clkout
index.

We can clean up the DPI driver's clock source handling by using the
dss_clk_source instead of only a dss_pll pointer.
This will also make it possible to use additional clock sources, like
PLL1_3 or HDMI_PLL, which the code did not support earlier.

The code to set the clock muxes for DISPC's LCD clock inputs is very
confusing. Especially on DRA7, there's an additional clock muxing that
needs to be done, which at the moment is done in dpi.c using
dss_ctrl_pll_set_control_mux().
Clean this all up by:
- Using dss_clk_source instead of dss_pll_id, as dss_pll_id doesn't
specify the clock source quite correctly.
- Splitting the dss_select_lcd_clk_source() up into DSS version specific
helper functions.
- Using dss_ctrl_pll_set_control_mux() from the helper functions, so
that dpi.c doesn't have to call it.

The names of the enum dss_clk_source's values are legacy names, only
correct for OMAP3 DSS. Rename the names to more generic ones.

'enum omap_dss_clk_source' is internal to dss. Let's rename it to
'dss_clk_source' match our naming convention.

The DSS output drivers check 'dssdev->manager' in disconnect()
functions. This check is not needed as the manager must always be set if
the output device was connected. Remove the check.

Both dpi and sdi check for 'mgr != NULL' in check_timings. This check is
not necessary, as mgr must always be set before check_timings. Remove
the check.

Now that omapfb has its own copy of omapdss and display drivers, we can
move omapdss and display drivers which omapdrm uses to omapdrm's
directory.
We also need to change the main drm Makefile so that omapdrm directory
is always entered, because omapdss has a file that can't be built as a
module.
