cpufreq: airoha: fix probe failure with correct error check

dev_pm_domain_attach_list() returns the number of attached PM domains
on success (a positive count), or a negative error code on failure.
The driver checks "if (ret)" which treats a successful attachment of
one or more PM domains as an error, causing the probe to fail with
return code 1.

Fix by checking "if (ret < 0)" like all other users of this API.
