kvm, arm: fix the size of MISCREG_FPSR and MISCREG_FPCR
Those registers are 32-bit instead of 64 in the KVM API.
The Linux kernel 5.2 linux/Documentation/virtual/kvm/api.txt contains:
0x6020 0000 0010 00d4 FPSR 32 fp_regs.fpsr
0x6020 0000 0010 00d5 FPCR 32 fp_regs.fpcr
The register itself is 64-bit in the ARM manual, but the top 32 are
RES0.
This fixes the following error when running ARM KVM early in the
simulation:
panic: KVM: Failed to set register (0x60300000001000d4) value
(errno: 22)
