The way to load the HQVDP firmware has been updated.
HQVDP firmware is now loaded the first time an HQVDP plane is used and
no more when the HQVDP driver is bound.
This solves the dependency we had on the file system availability.
The first time the HQVDP plane is used, we are sure that file system is
available so request_firmware function will match.
CONFIG_FW_LOADER_USER_HELPER_FALLBACK is then no more mandatory.

This patch uses an approach closer to the nvidia driver to configure
both PLLs for high gddr5 memory clocks (usually above 2400MHz)
Previously nouveau used the one PLL as it was used for the lower clocks
and just adjusted the second PLL to get as close as possible to the
requested clock. This means for my card, that I got a 4050 MHz clock
although 4008 MHz was requested.
Now the driver iterates over a list of PLL configuration also used by
the nvidia driver and then adjust the second PLL to get near the
requested clock. Also it hold to some restriction I found while
analyzing the PLL configurations
This won't fix all gddr5 high clock issues itself, but it should be
fine on hybrid gpu systems as found on many laptops these days. Also
switching while normal desktop usage should be a lot more stable than
before.

10053c is not even read on some cards, and I have no idea exactly what the

If the hardware supports extended tag field (8-bit ones), then enable it.
This is usually done by the VBIOS, but not on some MBPs (see fdo#86537).
In case extended tag field is not supported, 5-bit tag field is used which
limits the possible number of requests to 32. Apparently bits 7:0 of
0x08841c stores some number of outstanding requests, so cap it to 32 if
extended tag is unsupported.
