The base floating point, SVE and SME all have enable controls for EL0 and EL1 in CPACR_EL1 which have a similar layout and function. Currently the basic floating point enable FPEN is defined differently to the SVE control, specified as a single define in kvm_arm.h rather than in sysreg.h. Move the define to sysreg.h and provide separate EL0 and EL1 control bits so code managing the different floating point enables can look consistent.
