Pins are numbered in the R-Car family documentation using a bank number
and a pin number in the bank. As the Linux pin number space is linear,
we need to flatten this by multiplying the bank number by 32 and adding
the pin number. The resulting number bear no directly visible
relationship to the documentation, making it error-prone.
Add a RCAR_GP_PIN macro to convert from the documentation pin number
space to the linear Linux space.

... not the port clock. This allows us to kill the funny semantics
around pixel_target_clock.
Since the dpll code still needs the real port clock, add a new
port_clock field to the pipe configuration. Handling the default case
for that one is a bit tricky, since encoders might not consistently
overwrite it when retrying the crtc/encoder bw arbitrage step in the
compute config stage. Hence we need to always clear port_clock and
update it again if the encoder hasn't put in something more specific.
This can't be done in one step since the encoder might want to adjust
the mode first.
I was a bit on the fence whether I should subsume the pixel multiplier
handling into the port_clock, too. But then I decided against this
since it's on an abstract level still the dotclock of the adjusted
mode, and only our hw makes it a bit special due to the separate pixel
mulitplier setting (which requires that the dpll runs at the
non-multiplied dotclock).
So after this patch the adjusted_mode accurately describes the mode we
feed into the port, after the panel fitter and pixel multiplier (or
line doubling, if we ever bother with that) have done their job.
Since the fdi link is between the pfit and the pixel multiplier steps
we need to be careful with calculating the fdi link config.
v2: Fix up ilk cpu pll handling.
v3: Introduce an fdi_dotclock variable in ironlake_fdi_compute_config
to make it clearer that we transmit the adjusted_mode without the
pixel multiplier taken into account. The old code multiplied the the
available link bw with the pixel multiplier, which results in the same
fdi configuration, but is much more confusing.
v4: Rebase on top of Imre's is_cpu_edp removal.
v5: Rebase on top of Paulo's haswell watermark fixes, which introduce
a new place which looked at the pixel_clock and so needed conversion.
v6: Split out prep patches as requested by Paulo Zanoni. Also rebase
on top of the fdi dotclock handling fix in the fdi lanes/bw
computation code.

We currently mutliply the link_bw of the fdi link with the pixel
multiplier, which is wrong: The FDI link doesn't suddenly grow more
bandwidth. In reality the pixel mutliplication only happens in the PCH,
before the pixels are fed into the port.
But since we our code treats the uses the target clock after pixels
are doubled (tripled, ...) already, we need to correct this.
Semantically it's clearer to divide the target clock to get the fdi
dotclock instead of multiplying the bw, so do that instead.
Note that the target clock is already multiplied by the same factor,
so the division will never loose accuracy for the M/N computation.
The lane computation otoh used the wrong value, we also need to feed
the fdi dotclock to that.
Split out on a request from Paulo Zanoni.
v2: Also fix the lane computation, it used the target clock to compute
the bw requirements, not the fdi dotclock (i.e. adjusted with the
pixel multiplier). Since sdvo only uses the pixel multiplier for
low-res modes (with a dotclock below 100MHz) we wouldn't ever have
rejected a bogus mode, but just used an inefficient fdi config.
v3: Amend the commit message to explain better what the change for the
fdi lane config computation is all about. Requested by Paulo.
