target/armv7m: prevent saving and restoring non existent regs
armv7m_start_algorithm() saves register values to arch_info->context.
armv7m_wait_algorithm() restores register values from arch_info->context.
Exclude registers with flag exist = false from both loops.
While on it refactor the register restore: introduce 'struct reg' pointer
and dereference it instead of numerous accesses by a full path
from armv7m pointer.
