Sönke Holz 0c8c0ff412 Kernel/riscv64: Fix backtrace generation on RISC-V ...

RISC-V uses a different convention for storing stack frame information
described here: https://github.com/riscv-non-isa/riscv-elf-psabi-doc/blob/master/riscv-cc.adoc#frame-pointer-convention
This part of the psABI is not yet in a ratified version, but both GCC
and Clang seem to use this convention.

Note that the backtrace dumping code still won't work for the initial
stack, as it is located before `kernel_mapping_base`.
