SPM: Move shim layer to TTBR1_EL1
This gives each Secure Partition complete freedom on its address space.
Previously, the memory used by the exception vectors was reserved and
couldn't be used. Also, it always had to be mapped, forcing SPM to
generate translation tables that included the exception vectors as well
as the Partition memory regions. With this change, partitions can reduce
their address space size easily.

The comments in setjmp.h are no longer needed as there are no deviations

All SDEI code that relied on them has been fixed to use the new function
prototypes and structs.

This patch adds support to handle following TLK SMCs:
{TLK_SS_REGISTER_HANDLER, TLK_REGISTER_NS_DRAM_RANGES, TLK_SET_ROOT_OF_TRUST}
These SMCs need to be supported in ATF in order to forward them to
TLK. Otherwise, these functionalities won't work.
Brief:
TLK_SS_REGISTER_HANDLER: This SMC is issued by TLK Linux Driver to
set up secure storage buffers.
TLK_REGISTER_NS_DRAM_RANGES: Cboot performs this SMC during boot to
pass NS memory ranges to TLK.
TLK_SET_ROOT_OF_TRUST: Cboot performs this SMC during boot to pass
Verified Boot parameters to TLK.

This reverts commit 2f370465241c ("Add support for the SMC Calling

SMCCC v2.0 is no longer required for SPM, and won't be needed in the
future. Removing it makes the SMC handling code less complicated.
The SPM implementation based on SPCI and SPRT was using it, but it has
been adapted to SMCCC v1.0.
