David Gibson 0cbad81f70 pseries: Fixes and enhancements to L1 cache properties
PAPR requires that the device tree's CPU nodes have several properties
with information about the L1 cache.  We already create two of these
properties, but with incorrect names - "[id]cache-block-size" instead
of "[id]-cache-block-size" (note the extra hyphen).

We were also missing some of the required cache properties.  This
patch adds the [id]-cache-line-size properties (which have the same
values as the block size properties in all current cases).  We also
add the [id]-cache-size properties.

Adding the cache sizes requires some extra infrastructure in the
general target-ppc code to (optionally) set the cache sizes for
various CPUs.  The CPU family descriptions in translate_init.c can set
these sizes - this patch adds correct information for POWER7, I'm
leaving other CPU types to people who have a physical example to
verify against.  In addition, for -cpu host we take the values
advertised by the host (if available) and use those to override the
information based on PVR.
