347a5c73bafd1b5872c9d3192a4d08f8aa1d5f5a target/ppc: Add execute permission checking to access authority check
Basic storage protection defines various access authority permissions
based on a slb storage key and pte pp value pair. This access authority
defines read, write and execute permissions however currently we only
use this to control read and write permissions and ignore the execute
control.
Fix the code to allow execute permissions based on the key-pp value pair.
Execute is allowed under the same conditions which enable reads.
(i.e. read permission -> execute permission)
