The ARMv8.4-PMU extension adds:
* one new required event, STALL
* one new system register PMMIR_EL1
(There are also some more L1-cache related events, but since
we don't implement any cache we don't provide these, in the
same way we don't provide the base-PMUv3 cache events.)
The STALL event "counts every attributable cycle on which no
attributable instruction or operation was sent for execution on this
PE". QEMU doesn't stall in this sense, so this is another
always-reads-zero event.
The PMMIR_EL1 register is a read-only register providing
implementation-specific information about the PMU; currently it has
only one field, SLOTS, which defines behaviour of the STALL_SLOT PMU
event. Since QEMU doesn't implement the STALL_SLOT event, we can
validly make the register read zero.

The ARMv8.1-PMU extension requires:
* the evtCount field in PMETYPER<n>_EL0 is 16 bits, not 10
* MDCR_EL2.HPMD allows event counting to be disabled at EL2
* two new required events, STALL_FRONTEND and STALL_BACKEND
* ID register bits in ID_AA64DFR0_EL1 and ID_DFR0
We already implement the 16-bit evtCount field and the
HPMD bit, so all that is missing is the two new events:
STALL_FRONTEND
"counts every cycle counted by the CPU_CYCLES event on which no
operation was issued because there are no operations available
to issue to this PE from the frontend"
STALL_BACKEND
"counts every cycle counted by the CPU_CYCLES event on which no
operation was issued because the backend is unable to accept
any available operations from the frontend"
QEMU never stalls in this sense, so our implementation is trivial:
always return a zero count.

The AArch32 DBGDIDR defines properties like the number of
breakpoints, watchpoints and context-matching comparators. On an
AArch64 CPU, the register may not even exist if AArch32 is not
supported at EL1.
Currently we hard-code use of DBGDIDR to identify the number of
breakpoints etc; this works for all our TCG CPUs, but will break if
we ever add an AArch64-only CPU. We also have an assert() that the
AArch32 and AArch64 registers match, which currently works only by
luck for KVM because we don't populate either of these ID registers
from the KVM vCPU and so they are both zero.
Clean this up so we have functions for finding the number
of breakpoints, watchpoints and context comparators which look
in the appropriate ID register.
This allows us to drop the "check that AArch64 and AArch32 agree
on the number of breakpoints etc" asserts:
* we no longer look at the AArch32 versions unless that's the
right place to be looking
* it's valid to have a CPU (eg AArch64-only) where they don't match
* we shouldn't have been asserting the validity of ID registers
in a codepath used with KVM anyway

This is part of a reorganization to the set of mmu_idx.
This emphasizes that they apply to the EL1&0 regime.
The ultimate goal is
-- Non-secure regimes:
ARMMMUIdx_E10_0,
ARMMMUIdx_E20_0,
ARMMMUIdx_E10_1,
ARMMMUIdx_E2,
ARMMMUIdx_E20_2,
-- Secure regimes:
ARMMMUIdx_SE10_0,
ARMMMUIdx_SE10_1,
ARMMMUIdx_SE3,
-- Helper mmu_idx for non-secure EL1&0 stage1 and stage2
ARMMMUIdx_Stage2,
ARMMMUIdx_Stage1_E0,
ARMMMUIdx_Stage1_E1,
The 'S' prefix is reserved for "Secure". Unless otherwise specified,
each mmu_idx represents all stages of translation.

Rather than call to a separate function and re-compute any
parameters for the flush, simply use the correct flush
function directly.
