mips/kvm: Sync with newer MIPS KVM headers 



The KVM_REG_MIPS_COUNT_* definitions are now included in
linux-headers/asm-mips/kvm.h since commit b061808d ("linux-headers:
update linux headers to kvm/next"), therefore the duplicate definitions
in target-mips/kvm.c can now be dropped (the definitions were tweaked
slightly in commit 7a52ce8a ("linux-headers: update") which
triggered the following build warnings turned errors):

target-mips/kvm.c:232:0: error: "KVM_REG_MIPS_COUNT_CTL" redefined [-Werror]
linux-headers/asm/kvm.h:129:0: note: this is the location of the previous definition
target-mips/kvm.c:236:0: error: "KVM_REG_MIPS_COUNT_RESUME" redefined [-Werror]
linux-headers/asm/kvm.h:141:0: note: this is the location of the previous definition
target-mips/kvm.c:239:0: error: "KVM_REG_MIPS_COUNT_HZ" redefined [-Werror]
linux-headers/asm/kvm.h:147:0: note: this is the location of the previous definition

Also update the MIPS_C0_{32,64} macros to utilise definitions more
recently added to the asm-mips/kvm.h header.
