Timon Kruiper 247109cee6 Kernel/aarch64: Execute kernel with SP_EL1 instead of SP_EL0 ...

Until now the kernel was always executing with SP_EL0, as this made the
initial dropping to EL1 a bit easier. This commit changes this behaviour
to use the corresponding SP_ELx for each exception level.

To make sure that the execution of the C++ code can continue, the
current stack pointer is copied into the corresponding SP_ELx just
before dropping an exception level.
