hw/intc/arm_gic: Fix handling of NS view of GICC_APR<n>

In gic_cpu_read() and gic_cpu_write(), we delegate the handling of
reading and writing the Non-Secure view of the GICC_APR<n> registers
to functions gic_apr_ns_view() and gic_apr_write_ns_view().
Unfortunately we got the order of the arguments wrong, swapping the
CPU number and the register number (which the compiler doesn't catch
because they're both integers).

Most guests probably didn't notice this bug because directly
accessing the APR registers is typically something only done by
firmware when it is doing state save for going into a sleep mode.

Correct the mismatched call arguments.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
