Fabian Aggeler f0aff25570 target-arm: implement CPACR register logic for ARMv7
In ARMv7 the CPACR register allows to control access rights to
coprocessor 0-13 interfaces. Bits corresponding to unimplemented
coprocessors should be RAZ/WI. Bits ASEDIS, D32DIS, TRCDIS are
UNK/SBZP if VFP is not implemented and RAO/WI in some cases.
Treating TRCDIS as RAZ/WI since we neither implement a trace
macrocell nor a CP14 interface to the trace macrocell registers.

Since CPACR bits for VFP/Neon access are honoured with the CPACR_FPEN
bit in the TB flags, flushing the TLB is not necessary anymore.
