MIPS: Lantiq: fix missing xbar kernel panic
commit 6ef90877eee63a0d03e83183bb44b64229b624e6 upstream.
Commit 08b3c894e565 ("MIPS: lantiq: Disable xbar fpi burst mode")
accidentally requested the resources from the pmu address region
instead of the xbar registers region, but the check for the return
value of request_mem_region() was wrong. Commit 98ea51cb0c8c ("MIPS:
Lantiq: Fix another request_mem_region() return code check") fixed the
check of the return value of request_mem_region() which made the kernel
panics.
This patch now makes use of the correct memory region for the cross bar.
