[PATCH v3 07/10] ARM: tegra: tf701t: Fix BCM43341 WiFi/BT chip configuration

The BCM4334 chip's Bluetooth part does not support reset-gpio. This was
confirmed by testing on the TF701T, so drop reset-gpio from the Bluetooth
node to comply with the existing schema. Additionally, the BCM4334
supports an LPO clock, which is required for proper and stable operation
of WiFi and Bluetooth, so add it to both nodes. Lastly, the BCM4334 chip's
WiFi part has a dedicated compatible in the schema, so set
'brcm,bcm43340-fmac' as the primary compatible while 'brcm,bcm4329-fmac'
remains as a fallback.
