Resetting the USB device controller on boot is only necessary if the SoC
actually has a UDC controller and U-Boot enables support for it. All the
Tegra boards support UDC via the ChipIdea UDC driver, so make the UDC on
boot workaround depend on the ChipIdea UDC driver

Boards may not support all the boot target devices in the default list
for Tegra devices. Allow a board to override the list and default to the
standard list only if the board hasn't specified one itself.

The GP pad control code is not relevant on all Tegra SoC generations, so
guard it with a Kconfig symbol that can be selected by the generations
that need it.
This is in preparation for unifying Tegra186 code with the code used on
older generations.

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 a9819b9e33bd ("ARM: tegra: p2771-000:
increase max DRAM bank count"), t

There's no need to replicate the pmu.h header file for every Tegra SoC
generation. Use a single header that is shared across generations.

The bulk of these changes are an effort to unify Tegra186 builds with
builds of prior 64-bit Tegra generations. On top of that there are
various improvements that allow data (such as the MAC address and boot
arguments) to be passed through from early firmware to the kernel

pll_c is not a valid parent for the disp1 clock, so trying to set it
will fail. Given that display is not used in U-Boot, remove the init
table entry so that disp1 will keep its default parent (clk_m).
