It makes things a bit more standard and a bit nicer to read
without all those strlen(). Also console.c takes care of adding
the carriage returns before the linefeeds.

This uses the new header files for register definitions and
extracts the core frequency from syscon rather than hard coding it.

This adds a test that tries to execute various privileged instructions
with MSR[PR] = 1. This also incidentally tests some of the MSR bit
manipulations.

Checks interrupt masking and priorities.
Adds to `make test_xics` which is run in `make check` also.

This puts an attn instruction at offset 0x700 in each of the tests
so that the test will terminate if a program interrupt is taken.
This means that we can implement the tw instruction to cause a
program interrupt.

This fixes the decrementer, illegal and sc tests to compile
successfully with cross-compilers that don't provide unistd.h
or string.h. Instead of those headers we include stddef.h.
This also fixes tests/Makefile.test to do what one expects
when CROSS_COMPILE is defined in the environment.

This adds test cases for:
- sc, illegals and decrementer exceptions
- decrementer overflow
- rfid
- mt/mf sprg0/1 srr0/1
- mtdec
- mtmsrd
- sc
It also adds these test cases to make check/check_light

Right now our test cases fold the SPRs into the GPRs. That makes
debugging fails more difficult than it needs to be, so print
out the CTR, LR and CR.
We still need to print the XER, but that is in two spots in microwatt
and will take some more work.
This also adds many instructions to the tests that we have added
lately including overflow instructions, CR logicals and mt/mfxer.
