doc: qemu: fix and update documentation ...

The current URL for QEMU_EFI.fd is not found. Update the link to
point to the new one.

If you run the shell command as instructed, you will see this error:
  qemu-system-aarch64: keep_bootcon: Could not open 'keep_bootcon': No such file or directory

The part "console=ttyAMA0,38400 keep_bootcon root=/dev/vda2" is the
kernel parameter, so it must be quoted.

As of writing, QEMU v4.2.0 is the latest, but it does not work for
TF-A (It has been fixed in the mainline.) QEMU v4.1.0 works fine.

With those issues addressed, I succeeded in booting the latest kernel.

Tested with QEMU v4.1.0 and Linux 5.5 (defconfig with no modification).
Update the tested versions.

Tegra194: remove support for simulated system suspend ...

This patch removes support for simulated system suspend for Tegra194
platforms as we have actual silicon platforms that support this
feature now.

Tegra: compile PMC driver for Tegra132/Tegra210 platforms ...

The PMC driver is used only by Tegra210 and Tegra132 platforms. This
patch removes pmc.c from the common makefile and moves it to the
platform specific makefiles.

As a result, the PMC code from common code has been moved to Tegra132
and Tegra210 platform ports.

Tegra: remove weakly defined platform setup handlers ...

This patch converts the weakly defined platform setup handlers into
actual platform specific handlers to improve code coverage numbers
and some MISRA defects.

The weakly defined handlers never get executed thus resulting in
lower coverage - function, function calls, statements, branches
and pairs.

Tegra194 supports upto 64GB of DRAM, whereas the previous SoCs support
