ARM: tegra: CONFIG_{SYS_, }LOAD{_, }ADDR rationalization

As best I can tell, CONFIG_SYS_LOAD_ADDR and CONFIG_LOADADDR/$loadaddr
serve essentially the same purpose. Roughly, if a command takes a load
address, then CONFIG_SYS_LOAD_ADDR or $loadaddr (or both) are the default
if the command-line does not specify the address. Different U-Boot
commands are inconsistent re: which of the two default values they use.
As such, set the two to the same value, and move the logic that does this
into tegra-common-post.h so it's not duplicated. A number of other non-
Tegra boards do this too.

The values chosen for these macros are no longer consistent with anything
in MEM_LAYOUT_ENV_SETTINGS. Regain consistency by setting $kernel_addr_r
to CONFIG_LOADADDR. Older scripts tend to use $loadaddr for the default
kernel load address, whereas newer scripts and features tend to use
$kernel_addr_r, along with other variables for other purposes such as
DTBs and initrds. Hence, it's logical they should share the same value.

I had originally thought to make the $kernel_addr_r and CONFIG_LOADADDR
have different values. This would guarantee no interference if a script
used the two variables for different purposes. However, that scenario is
unlikely given the semantic meaning associated with the two variables.
The lowest available value is 0x90200000; see comments for
MEM_LAYOUT_ENV_SETTINGS in tegra30-common-post.h for details. However,
that value would be problematic for a script that loaded a raw zImage to
$loadaddr, since it's more than 128MB beyond the start of SDRAM, which
would interfere with the kernel's CONFIG_AUTO_ZRELADDR. So, let's not do
that.

The only potential fallout I could foresee from this patch is if someone
has a script that loads the kernel to $loadaddr, but some other file
(DTB, initrd) to a hard-coded address that the new value of $loadaddr
interferes with. This seems unlikely. A user should not do that; they
should either hard-code all load addresses, or use U-Boot-supplied
variables for all load addresses. Equally, any fallout due to this change
is trivial to fix; simply modify the load addresses in that script.

ARM: tegra: set initrd_high so boot scripts work

During bootm/z, U-Boot relocates the DTB and initrd to high memory so
they are out of the way of the kernel. On ARM at least, some parts of
high memory are "highmem" and can't be accessed at early boot. To solve
this, we need to restrict this relocation process to use lower parts of
RAM that area accessible.

For the DTB, an earlier patch of mine set CONFIG_SYS_BOOTMAPSZ. However,
since some platforms have different restrictions on DTB and initrd
location, that config option doesn't affect the initrd. We need to set
the initrd_high environment variable to control the initrd relocation.

Since we have carefully chosen the load addresses for the DTB and
initrd (see comments in include/configs/tegraNNN-common.h re: values in
MEM_LAYOUT_ENV_SETTINGS), we don't actually need any DTB or initrd
relocation at all. Skipping relocation removes some redundant work.
Hence, set both fdt_high and initrd_high to ffffffff which completely
disables relocation.

If the user does something unusual, such as using custom locations for
the DTB/initrd load address or wanting to use DTB/initrd relocation for
some reason, they can simply set these variables to custom values to
override these environment defaults.

With this change, cmd_sysboot works correctly for a filesystem created
by the Fedora installer.
