Since commit aa06a9bd8533 ("ia64: fix clock_getres(CLOCK_MONOTONIC) to
report ITC frequency"), gcc 10.1.0 fails to build ia64 with the gnomic:
| ../arch/ia64/kernel/sys_ia64.c: In function 'ia64_clock_getres':
| ../arch/ia64/kernel/sys_ia64.c:189:3: error: a label can only be part of a statement and a declaration is not a statement
| 189 | s64 tick_ns = DIV_ROUND_UP(NSEC_PER_SEC, local_cpu_data->itc_freq);
This line appears immediately after a case label in a switch.
Move the declarations out of the case, to the top of the function.

This patch was previously posted as a fix here:
https://www.spinics.net/lists/linux-ia64/msg21920.html
Its included here to keep the kbuild robot quiet.
