arm: Move systick device creation from NVIC to ARMv7M object

There's no particular reason why the NVIC should be owning the
SysTick device objects; move them into the ARMv7M container object
instead, as part of consolidating the "create the devices which are
built into an M-profile CPU and map them into their architected
locations in the address space" work into one place.

This involves temporarily creating a duplicate copy of the
nvic_sysreg_ns_ops struct and its read/write functions (renamed as
v7m_sysreg_ns_*), but we will delete the NVIC's copy of this code in
a subsequent patch.
