mt76: mt7615: disable merge of OTP ROM data by default

The reference driver does not seem to enable it by default, only under certain
conditions, e.g. when a .bin file is loaded.
Make it opt-in via a device tree property for now, in case it is needed on some
boards.

mt76: mt7615: Delete an error message in mt7622_wmac_probe()

The function “platform_get_irq” can log an error already.
Thus omit a redundant message for the exception handling in the
calling function.

This issue was detected by using the Coccinelle software.

mt76: mt7615: do not always reset the dfs state setting the channel

mac80211/hostapd runs mt7615_set_channel with the same channel
parameters sending multiple rdd commands overwriting the previous ones.
This behaviour is causing tpt issues on dfs channels.
Fix the issue checking new channel freq/width with the running one.
