Copying flags directly from msr has drawbacks: (1) msr bits
mean different things per cpu, (2) msr has 64 bits on 64 cpus
while tb->flags has only 32 bits.
Create a enum to define these bits. Document the origin of each bit
and validate those bits that must match MSR. This fixes the
truncation of env->hflags to tb->flags, because we no longer
have hflags bits set above bit 31.
Most of the code in ppc_tr_init_disas_context is moved over to
hreg_compute_hflags. Some of it is simple extractions from msr,
some requires examining other cpu flags. Anything that is moved
becomes a simple extract from hflags in ppc_tr_init_disas_context.
Several existing bugs are left in ppc_tr_init_disas_context, where
additional changes are required -- to be addressed in future patches.

Each vCPU core exposes its timebase frequency in the DT. When running
under KVM, this means parsing /proc/cpuinfo in order to get the timebase
frequency of the host CPU.
The parsing appears to slow down the boot quite a bit with higher number
of cores:
# of cores seconds spent in spapr_dt_cpus()
8 0.550122
16 1.342375
32 2.850316
64 5.922505
96 9.109224
128 12.245504
256 24.957236
384 37.389113
The timebase frequency of the host CPU is identical for all
cores and it is an invariant for the VM lifetime. Cache it
instead of doing the same expensive parsing again and again.
Rename kvmppc_get_tbfreq() to kvmppc_get_tbfreq_procfs() and
rename the 'retval' variable to make it clear it is used as
fallback only. Come up with a new version of kvmppc_get_tbfreq()
that calls kvmppc_get_tbfreq_procfs() only once and keep the
value in a static.
Zero is certainly not a valid value for the timebase frequency.
Treat atoi() returning zero as another parsing error and return
the fallback value instead. This allows kvmppc_get_tbfreq() to
use zero as an indicator that kvmppc_get_tbfreq_procfs() hasn't
been called yet.
