target-arm: Remove ARM_CPUID_* macroscp15-rework
All the uses of ARM_CPUID() to vary behaviour have now been removed, so we can delete the ARM_CPUID_* macros now. The one exception is the TI915T/925T, because of its odd behaviour where the MIDR value can be changed at runtime. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
