While converting the rest of the driver to use GRAPHICS_VER() and
MEDIA_VER(), following what was done for display, some discussions went
back on what we did for display:
1) Why is the == comparison special that deserves a separate
macro instead of just getting the version and comparing directly
like is done for >, >=, <=?
2) IS_DISPLAY_RANGE() is weird in that it omits the "_VER" for
brevity. If we remove the current users of IS_DISPLAY_VER(), we
could actually repurpose it for a range check
With (1) there could be an advantage if we used gen_mask since multiple
conditionals be combined by the compiler in a single and instruction and
check the result. However a) INTEL_GEN() doesn't use the mask since it
would make the code bigger everywhere else and b) in the cases it made
sense, it also made sense to convert to the _RANGE() variant.
So here we repurpose IS_DISPLAY_VER() to work with a [ from, to ] range
like was the IS_DISPLAY_RANGE() and convert the current IS_DISPLAY_VER()
users to use == and != operators. Aside from the definition changes,
this was done by the following semantic patch:

In order to avoid excessive boilerplate I changed the behaviour
such that all platforms now do the readout via
crtc_state->port_dpll[].
ICL+ TC is still a bit special due to TBTPLL not having a functional

On platforms/outputs without a working frame counter we rely
on the vblank code to cook up the frame counter from the timestamps.
That requires that vblank support is enabled. Thus we need to
move the pipe enable/disable tracepoints to the other side
of the drm_vblank_{on,off}() calls. There shouldn't really be
much happening between these old and new call sites so the
tracepoints should still provide reasonable data.
The alternative would be to give up on having the frame counter
values in the trace which would render the tracepoints more or
less pointless.

and ICL_DPCLKA_CFGCR0_TC_CLK_OFF part form icl_{map,unmap}_plls_to_ports()
2) ICL/TGL combo DDI + combo PHY
-> just need the stuff from icl_{map,unmap}_plls_to_ports()
3) JSL/EHL TC DDI + combo PHY
-> needs DDI_CLK_SEL==MG part from intel_ddi_clk_{select,disable}() and
the full combo style clock selection from icl_{map,unmap}_plls_to_ports()
4) ADLS/RKL
-> these use both TC and combo DDIs with combo PHYs, however they
always use the full combo style clock selection as per
icl_{map,unmap}_plls_to_ports() and do not use DDI_CLK_SEL at all,
thus get treated the same as 2)
We extract all that from the current mess in the following way:
1) icl_ddi_tc_{enable,disable}_clock()
2) icl_ddi_combo_{enable,disable}_clock()
3) jsl_ddi_tc_{enable,disable}_clock()
