fix(el3-spmc): use write_el1_ctx_timer() macro to set cntkctl_el1 value

commit 42e35d2f8c0e
("refactor(cm): convert el1 ctx assembly offset entries to c structure")
moves cntkctl_el1 register from el1_sysregs_t's common to arch_timer
structure.
To set cntkctl_el1, it should use write_el1_ctx_timer() instead of
write_el1_ctx_common() otherwise, build failed.
