When converting the CP15 registers from a struct to an array,
the TTBR registers have been accidently converted from a u64
to a u32. This introduced a subtle regression preventing
an LPAE guest from booting, and possibly some other side effects.
Add two placeholders in the cp15_regs union to reserve additionnal
entries in the cp15 register arrau.
