Peter Maydell d28059f4ea target/arm: Use correct variable for setting 'max' cpu's ID_AA64DFR0 
In aarch64_max_initfn() we update both 32-bit and 64-bit ID
registers. The intended pattern is that for 64-bit ID registers we
use FIELD_DP64 and the uint64_t 't' register, while 32-bit ID
registers use FIELD_DP32 and the uint32_t 'u' register. For
ID_AA64DFR0 we accidentally used 'u', meaning that the top 32 bits of
this 64-bit ID register would end up always zero. Luckily at the
moment that's what they should be anyway, so this bug has no visible
effects.

Use the right-sized variable.
