Don't allow conversion from arbitraty encoder types to a digital port.
Calling enc_to_dig_port() with the wrong encoder may seem far fetched,
but certain paths of the ddi code may be called with hasell's analog
encoder and the conversion is wrong for DP mst encoders too, so safe
guard against it.

Nitpick: for UNKNOWN could've added a WARN_ON(!DDI) check. Either way:

In Geminilake, the DDI IO power domains can't be enabled before a DPLL
is running and mapped to the appropriate DDI. At least on Geminilake,
attempting to enable those during init will lead to a timeout.
The failure to enable the power domain also causes issues with the state
verifier during resume from suspend. After all the init power domains
are enabled, the call to intel_power_domains_sync_hw() from the resume
path will cause the hw_enabled field on the respective power wells to be
false while the usage count remains above zero. Further attempts to
enable the power domain caused by a modeset will simply update the usage
count without doing anything else. When the state verifier attempts to
read the state of a DDI encoder, intel_display_power_get_if_enabled()
returns false, leading to the following WARN:

According to bspec, the DDI IO power domains should be enabled after
enabling the DPLL and mapping it to the DDI. The current order doesn't
seem to create problems with Skylake and Kabylake, but causes enable
timeouts in Geminilake.
v2: Rebase.
- Take power domain references before sanitizing encoders. (Imre)
- Add comment to get_encoder_power_domains() defition. (Ander)
v3: Don't put the domain if called with HSW/BDW's analog encoder. (CI)

This matters only for GEN9_BC but there this comes before the PLL to
port mapping is reset according to bspec.

To: intel-gfx; +Cc: Ander Conselvan de Oliveira
According to bspec, the DDI IO power domains should be enabled after
enabling the DPLL and mapping it to the DDI. The current order doesn't
seem to create problems with Skylake and Kabylake, but causes enable
timeouts in Geminilake.
v2: Rebase.
- Take power domain references before sanitizing encoders. (Imre)
- Add comment to get_encoder_power_domains() defition. (Ander)
v3: Don't put the domain if called with HSW/BDW's analog encoder. (CI)
v4: Put IO power domain before unmapping DPLL. (Imre)
- Change return type of intel_ddi_get_power_domains() to u64. (Imre)

This one seems to kill SKL+MST.
Just load the driver with an MST display plugged in and we get:
[ 79.389527] Kernel panic - not syncing: Timeout: Not all CPUs entered broadcast exception handler
So presumably we're trying to access something that's not powered/clocked
and the CPU just gets totally stuck.
