R-Car H2 (r8a7790) contains four Cortex-A15 and four Cortex-A7 cores,
hence the second interrupt specifier cell for Private Peripheral
Interrupts should use "GIC_CPU_MASK_SIMPLE(8)", to make sure interrupts
can be delivered to all 8 processor cores.

Untested
v2:
- Drop RFC status after receiving confirmation from Liviu Dudau.
