soc/nvidia/tegra124: remove cache_policiy option

All mainboards (nyans) utilizing the cache_policy option
has it set to DCACHE_WRITETHROUGH. This option is for setting
the framebuffer's cache attribute. However, this option is
reliant on an architecture-specific enumeration. Just remove
the option and use DCACHE_WRITETHROUGH across the board. If
someone wants to reconfigure it at a later date one can
introduce a non-architecture specific option.
