Subject: [PATCH] mt76: mt7615: avoid polling in fw_own for mt7663
Git-commit: 757b0e7fd6f4f2e558fac602ea34a9be20143c95
Patch-mainline: v5.9-rc1
References: jsc#SLE-13430
According to the vendor sdk, mt7663 does not need to poll register after
firmware own. Since just mt7622 polls status register, set proper
timeout value according to the vendor sdk
