fix(tc): remove timer interrupt from G1S

TC3 and TC4 SCP makes use of the system timer interrupt as its own
timer. Previously, this timer was marked as a G1S interrupt which
routes the interrupt to the secure world and also enables it. This
causes spurious interrupts once the SCP has unmasked the interrupt in
the timer control itself.

Note that we move the inclusion of the timer interrupt from
CSS_G1S_INT_PROPS to CSS_G1S_IRQ_PROPS as the former is only used by TC.
This will also result in removing the timer interrupt from TC2. This is
not an issue as it does not make use of this interrupt in either the SCP
or AP.
