[LEDE-DEV] [PATCH 3/6] uboot-lantiq: VGV7510KW22 - cleanup board config

[Mathias Kresin]

According to the author, all SPI related configs are copy & paste
leftovers. Which makes sense since nothing is connected to the SPI bus
on this device.

The NOR SPL isn't required for this board, since the NOR is directly
memory mapped.

Allow to overwrite the env in ram while using brn variant. Do not set
the power GPIO pin twice.
