ARM: tegra: Make cache line size SoC specific

Currently all Tegra SoCs are assumed to have 32 byte cache lines. This
isn't true for Tegra114, however, which uses 4 Cortex-A15 cores and
therefore uses a cache line size of 64 bytes. Move the cache line size
setting to the per-SoC common configuration file.
