Subject: [PATCH 1/2] openfw: Ensure get_devargs and get_devname functions are
 consistent

Commit 165c9b234 changed the logic of ieee1275_get_devargs() to use the
first or second occurrence of a colon as a separator between device name
and arguments. However, this didn't align with the complementary
function ieee1275_get_devname, which uses the first occurrence of a
colon after the namespace keyword as arguments for the nvme-of device.

This commit addresses the inconsistency by ensuring that both functions
follow a common logic. Now, get_devargs and get_devname functions are
consistent with each other, making it easier to understand and maintain
the codebase.
