When FEAT_SEL2 was implemented the SEL2 timers were missed. This
shows up when building the latest Hafnium with SPMC_AT_EL=2. The
actual implementation utilises the same logic as the rest of the
timers so all we need to do is:
- define the timers and their access functions
- conditionally add the correct system registers
- create a new accessfn as the rules are subtly different to the
existing secure timer
Fixes: e9152ee91c (target/arm: add ARMv8.4-SEL2 system registers)
