dts: Simplify bootargs

Reduce the number of different places that bootargs is set in Pi dts files. The variants are all combinations of with/without Bluetooth and with/without NUMA support (2711). This is effectively a cosmetic change - the resulting dtbs are unchanged. Signed-off-by: Phil Elwell <[email protected]>
