Up to now the RAM size of the sandbox is hard coded as 128 MiB. This does
not allow testing the correct handling of addresses outside the 32bit
range. 128 MiB is also rather small when tracing functions where the trace
is written to RAM.
Provide configuration variable CONFIG_SANDBOX_RAM_SIZE_MB to set the RAM
size in MiB. It defaults to 128 MiB with a minimum of 64 MiB.

This type of bus is used in Linux to designate buses which have power
domains and/or clocks which need to be enabled before their child devices
can be used. Because power domains are automatically enabled before probing
in U-Boot, we just need to enable any clocks present.

There can be different types of interrupt controllers in a system and some
drivers may need to distinguish between these. In general this can be
handled using the device tree by adding the interrupt information to
device nodes.
However on x86 devices we have interrupt controllers which are not tied
to any particular device and not really used in U-Boot. These still need
to be inited, so a convenient method is to give each controller a type
and allow a particular controller type to be probed.
Add support for this in sandbox along with a test.

At present if one of the initcalls fails on sandbox the address printing
is not help, e.g.:
initcall sequence 0000557678967c80 failed at call 00005576709dfe1f (err=-96)
This is because U-Boot gets relocated high into memory and the relocation
offset (gd->reloc_off) does not work correctly for sandbox.
Add support for finding the base address of the text region (at least on
Linux) and use that to set the relocation offset. This makes the output
better:
initcall sequence 0000560775957c80 failed at call 0000000000048134 (err=-96)
Then you use can use grep to see which init call failed, e.g.:
$ grep 0000000000048134 u-boot.map
stdio_add_devices
Of course another option is to run it with a debugger such as gdb:
$ gdb u-boot
...
