Instead of using switch..case for architecture defined exceptions,
simply unify the handling by printing a message of exception name,
followed by registers dump then halt the CPU.
With this unification, it also fixes the wrong exception numbers
for #MF/#AC/#MC/#XM which should be 16/17/18/19 not 15/16/17/18.

Some exceptions cause an error code to be saved on the current stack
after the EIP value. We should extract CS/EIP/EFLAGS from different
position on the stack based on the exception number.

Due to dependencies between timer and CPU frequency, only changes by

The encoding of the sub instruction used to handle CONFIG_SYS_MALLOC_F_LEN
can only accept certain values, and the set of acceptable values differs
between the AArch32 and AArch64 instructions sets. The default value of
CONFIG_SYS_MALLOC_F_LEN works with either ISA. Tegra uses a non-default
value that can only be encoded in the AArch32 ISA. Fix the AArch64 crt0
assembly so it can handle completely arbitrary values.

The sysboot and pxe commands currently support either U-Boot formats or
raw zImages. Add support for the AArch64 Linux port's native image format
too.
As with zImage support, there is no auto-detection of the native image
format. Rather, if the image is auto-detected as a U-Boot format, U-Boot
will try to interpret it as such. Otherwise, U-Boot will fall back to a
raw/native image format, if one is enabled.
My belief is that CONFIG_CMD_BOOTZ won't ever be enabled for any AArch64
port, hence there's never a need to differentiate between CONFIG_CMD_
_BOOTI and _BOOTZ at run-time; compile-time will do. Even if this isn't
true, we want to prefer _BOOTI over _BOOTZ when defined, since _BOOTI is
definitely the native format for AArch64.

In order to achieve reproducible builds in U-Boot, timestamps that are defined
at build-time have to be somewhat eliminated. The SOURCE_DATE_EPOCH environment
variable allows setting a fixed value for those timestamps.
Simply by setting SOURCE_DATE_EPOCH to a fixed value, a number of targets can be
built reproducibly. This is the case for e.g. sunxi devices.
However, some other devices might need some more tweaks, especially regarding
the image generation tools.
