Save P0-15 whose length is maximum 256 bits each, in this case the memory used is from the fpregs field in struct vfp_state, because V0-31 are part of Z0-31 and this space would have been unused for SVE domain otherwise. Create zcr_el{1,2} fields in arch_vcpu, initialise zcr_el2 on vcpu creation given the requested vector length and restore it on context switch, save/restore ZCR_EL1 value as well.

The field is used also to allow or forbid a domain to use SVE, because a value equal to zero means the guest is not allowed to use the feature. Check that the requested vector length is lower or equal to the platform supported vector length, otherwise fail on domain creation. Check that only 64 bit domains have SVE enabled, otherwise fail.

While there, correct coding style for the comment on coprocessor trapping. Now cptr_el2 is part of the domain context and it will be restored on context switch, this is a preparation for saving the SVE context which will be part of VFP operations, so restore it before the call to save VFP registers. To save an additional isb barrier, restore cptr_el2 before an existing isb barrier and move the call for saving VFP context after that barrier. To keep a (mostly) specularity of ctxt_switch_to() and ctxt_switch_from(), move vfp_save_state() up in the function. Change the KConfig entry to make ARM64_SVE symbol selectable, by default it will be not selected. Create sve module and sve_asm.S that contains assembly routines for the SVE feature, this code is inspired from linux and it uses instruction encoding to be compatible with compilers that does not support SVE, imported instructions are documented in README.LinuxPrimitives.
