lantiq: lzma-loader: fix O32 ABI conformance
According to the calling convention of the o32 ABI the
caller function must reserve stack space for $a0-$a3
registers in case the callee needs to save its arguments.
The assembly startup code does not reserve stack space
for these registers thus when the main C function needs
to save its arguments, that will cause a stack overflow.
Fix the assembly code to reserve stack space for the
registers to avoid that.
Compile tested only.
