[SLOF] [PATCH] Fix bad assembler statements for compiling with gcc 8.1 / as 2.30

When compiling with a very recent toolchain, I get these warnings:
../../llfw/boot_abort.S: Assembler messages:
../../llfw/boot_abort.S:76: Warning: invalid register expression
and:
stage2_head.S: Assembler messages:
stage2_head.S:57: Warning: invalid register expression
The first one is using the wrong opcode, we should use "and" instead of
"andi" here. The second one is using a register instead of a constant
for load-immediate, which is non-sense, too. Fix it to use the right
constant instead.
