MIPS: Support recognition of the DSP ASE at run-time
Add detection of MIPS DSPr2 at run-time in qsimd.cpp. This makes it
possible to have generic Qt builds for MIPS that can enable the fast
code paths for processors with the DSP ASE at run-time. Also, this
makes it possible to manually disable them by setting the environment
variable "QT_NO_CPU_FEATURE=dspr2". Last, but not least, functions
requiring DSPr2 are not enabled when running in CPUs with version-1
DSP.
