Mark Salter b2fc0a13f9 drivers/perf: xgene_pmu: Fix uninitialized resource struct 
[ Upstream commit a76b8236edcf5b785d044b930f9e14ad02b4a484 ]

This splat was reported on newer Fedora kernels booting on certain
X-gene based machines:

 xgene-pmu APMC0D83:00: X-Gene PMU version 3
 Unable to handle kernel read from unreadable memory at virtual \
 address 0000000000004006
 ...

 ---[ end trace f08c10566496a703 ]---

This is due to use of an uninitialized local resource struct in the xgene
pmu driver. The thunderx2_pmu driver avoids this by using the resource list
constructed by acpi_dev_get_resources() rather than using a callback from
that function. The callback in the xgene driver didn't fully initialize
the resource. So get rid of the callback and search the resource list as
done by thunderx2.
