ARM: tegra: Unify Tegra186 builds
Tegra186 build are currently dealt with in very special ways, which is
because Tegra186 is fundamentally different in many respects. It is no
longer necessary to do many of the low-level programming because early
boot firmware will already have taken care of it.
Unfortunately, separating Tegra186 builds from the rest in this way
makes it difficult to share code with prior generations of Tegra. With
all of the low-level programming code behind Kconfig guards, the build
for Tegra186 can again be unified.
As a side-effect, and partial reason for this change, other Tegra SoC
generations can now make use of the code that deals with taking over a
boot from earlier bootloaders. This used to be nvtboot, but has been
replaced by cboot nowadays. Rename the files and functions related to
this to avoid confusion. The implemented protocols are unchanged.

ARM: tegra: Restore DRAM bank count
Commit
86cf1c82850f ("configs: Migrate CONFIG_NR_DRAM_BANKS") reduced
the number of DRAM banks supported by U-Boot from 1026 to 8 on P2771-000
boards.
However, as explained in commit

unusable chunks of memory (up to 1024), so a total of 1026 DRAM banks

In practice the number of DRAM banks needed will typically be much

The current code using generic helpers only works for PHYs that have

"
Fix this by reverting to use the raw MDIO bus operations in case there
is no PHY probed based on DT at the specified address.
This restores the old behavior for these PHYs, which means that the
newly introduced MMD-over-C22 helpers won't be available for them, but
at least they will be accessible again without crashing the system.
