x86_cpu_get_supported_cpuid() is generic and handles the different
accelerators. Use it instead of kvm_arch_get_supported_cpuid().
That fixes a link failure introduced by commit 3adce820cf
("target/i386: Remove unused KVM stubs") when QEMU is configured
as:
$ ./configure --cc=clang \
--target-list=x86_64-linux-user,x86_64-softmmu \
--enable-debug
We were getting:

clang: error: linker command failed with exit code 1 (use -v to see invocation)

For the record, this is because '--enable-debug' disables
optimizations (CFLAGS=-O0).
While at this (un)optimization level GCC eliminate the
following dead code (CPP output of mentioned build):
static void x86_cpu_get_supported_cpuid(uint32_t func, uint32_t index,
uint32_t *eax, uint32_t *ebx,
uint32_t *ecx, uint32_t *edx)

Clang does not (see commit 2140cfa51d "i386: Fix build by
providing stub kvm_arch_get_supported_cpuid()").

Enabling AP-passthrough(AP-pt) for PV-guest by using the new CPU
features for PV-AP-pt of KVM.
As usual QEMU first checks which CPU features are available and then
sets them if available and selected by user. An additional check is done
to verify that PV-AP can only be enabled if "regular" AP-pt is enabled
as well. Note that KVM itself does not enforce this restriction.

kvm_s390_set_attr() is a misleading name as it only sets attributes for
the KVM_S390_VM_CRYPTO group. Therefore, rename it to
kvm_s390_set_crypto_attr().
Add new functions ap_available() and ap_enabled() to avoid code
duplication later.

"For CSRRWI, if rd=x0, then the instruction shall not read the CSR and
shall not cause any of the side effects that might occur on a CSR read."
trans_csrrwi() and trans_csrrw() call do_csrw() if rd=x0, do_csrw() calls
riscv_csrrw_do64(), via helper_csrw() passing NULL as *ret_value.
