Program display related vregs to proper value at initialization, setup

vGPU virtual display vregs inherit the value from pregs. The virtual DP
monitor is always setup on PORT_B for BXT/APL. However the host may
connect monitor on other PORT or without any monitor connected. Without
properly setup PIPE/DDI/PLL related vregs, guest driver may not setup
the virutal display as expected, and the guest desktop may not be
created.

enable transcoder/DDI/PLL based on which port is setup for BXT/APL.

commit e7c6e405e1 upstream.
It seems like Fedora 34 ends up enabling a few new gcc warnings, notably
"-Wstringop-overread" and "-Warray-parameter".
Both of them cause what seem to be valid warnings in the kernel, where
we have array size mismatches in function arguments (that are no longer
just silently converted to a pointer to element, but actually checked).
This fixes most of the trivial ones, by making the function declaration
match the function definition, and in the case of intel_pm.c, removing
the over-specified array size from the argument declaration.
At least one 'stringop-overread' warning remains in the i915 driver, but
that one doesn't have the same obvious trivial fix, and may or may not
actually be indicative of a bug.

[ Upstream commit 68eb3ae3c6 ]
When encoder validation of a display mode fails, retry with less bandwidth
heavy YCbCr420 color mode, if available. This enables some HDMI 1.4 setups
to support 4k60Hz output, which previously failed silently.
On some setups, while the monitor and the gpu support display modes with
pixel clocks of up to 600MHz, the link encoder might not. This prevents
YCbCr444 and RGB encoding for 4k60Hz, but YCbCr420 encoding might still be
possible. However, which color mode is used is decided before the link
encoder capabilities are checked. This patch fixes the problem by retrying
to find a display mode with YCbCr420 enforced and using it, if it is
valid.

rq_param->misc.rq_c.blk256_height is 0 when chroma(*_c) is invalid.

Fix applied on all dml versions.
1. Ensure dml_log2 is only called if the argument is greater than 0.
2. Subtract req128_l/req128_c from log2_swath_height_l/log2_swath_height_c

[ Upstream commit 2ad52bdb22 ]
Leaving this at a close-to-maximum register value 0xFFF0 means it takes
very long for the MDSS to generate a software vsync interrupt when the
hardware TE interrupt doesn't arrive. Configuring this to double the
vtotal (like some downstream kernels) leads to a frame to take at most
twice before the vsync signal, until hardware TE comes up.
In this case the hardware interrupt responsible for providing this
signal - "disp-te" gpio - is not hooked up to the mdp5 vsync/pp logic at
all. This solves severe panel update issues observed on at least the
Xperia Loire and Tone series, until said gpio is properly hooked up to
an irq.
