rockchip: puma-rk3399: allow loading environment from SPI-NOR flash
There's a SPI-NOR flash available from which SPL and U-Boot proper can
be booted, it makes sense to also allow this medium to store U-Boot
environment so let's enable it.
The Device Tree advertises a max frequency of 50MHz so let's set the
config option appropriately.
