selftests/powerpc: Use req_max_processed_len from sysfs NX capabilities
...
On PowerVM, the hypervisor defines the maximum buffer length for
each NX request and the kernel exported this value via sysfs.
This patch reads this value if the sysfs entry is available and
is used to limit the request length.

selftests/powerpc: Use proper error code to check fault address
...
ERR_NX_TRANSLATION(CSB.CC=5) is for internal to VAS for fault handling
and should not used by OS. ERR_NX_AT_FAULT(CSB.CC=250) is the proper
error code should be reported by OS when NX encounters address
translation failure.
This patch uses CC=250 to determine the fault address when the request
is not successful.
