After commit 1c74eeaf16 ("drm/i915: Move number of scalers initialization to
runtime init"), scalers are not initialized properly for skl and glk
since num_scalers is left as 0 for those platforms.

In future patches, we require greater flexibility in describing
the number of scalers available on each CRTC. To ease that transition
we move the current assignment to intel_device_info.
Scaler structure initialisation is done if scaler is available on the CRTC.
Gen9 check is not required as on depending upon numbers of scalers we
initialize scalers or return without doing anything in skl_init_scalers.
v3: Changed skl_init_scaler to intel_crtc_init_scalers
v2: Added Chris's comments.

The platform flags in device info are (mostly) mutually
exclusive. Replace the flags with an enum. Add the platform enum also
for platforms that previously didn't have a flag, and give them codename
logging in dmesg.
Pineview remains an exception, the platform being G33 for that.
v2: Sort enum by gen and date
v3: rebase on geminilake enabling

Get rid of SEP_SEMICOLON and SEP_BLANK in DEV_INFO_FOR_EACH_FLAG.
Consolidate the debug output so that instead of one huge line with
"cap1,cap2,capN" each capability is split to own line and displayed
as "capN: [yes|no]" to make the dumps more historically informative.

Fix sparse warning:
drivers/gpu/drm/i915/intel_device_info.c:195:31: warning: Variable
length array is used.
In truth the array does have constant length, but sparse is too dumb to
realize. This is a bit ugly, but silence the warning no matter what.

In an upcoming patch we'll need the actual mask of subslices in addition
to their count, so convert the subslice_per_slice field to a mask.
Also we can easily calculate subslice_total from the other fields, so
instead of storing a cached version of this, add a helper to calculate
it.
v2:
- Use hweight8() on u8 typed vars instead of hweight32(). (Ben)
