[PATCH net 1/2] net: ipa: Fix programming of QTIME_TIMESTAMP_CFG

[Luca Weiss]

The 'val' variable gets overwritten multiple times, discarding previous
values. Looking at the git log shows these should be combined with |=
instead.

Fixes: 9265a4f0f0b4 ("net: ipa: define even more IPA register fields")
