core/cortex-m[0]: Replace calculation with variable for readability
PANIC_DATA_PTR is defined as
((struct panic_data *)CONFIG_PANIC_DATA_BASE)
which is
CONFIG_RAM_BASE + CONFIG_RAM_SIZE - CONFIG_PANIC_DATA_SIZE
Instead of doing that calculation again, just re-use
PANIC_DATA_PTR, which more clearly shows the relationship between
pdata_ptr and pstack_addr. As indicated by the TEST line, this results
in no change to the generated code.
