Remove two unused bs handles

Add initial support for ARMv8 (AARCH64) (by nisimura@ and ryo@)

- sys/arch/evbarm64 is gone and integrated into sys/arch/evbarm. (by skrll@)
- add support fdt. evbarm/conf/GENERIC64 fdt (bcm2837,sunxi,tegra) based generic 64bit kernel config. (by skrll@, jmcneill@)

Get rid of tegra_chip_id/tegra_chip_name and rely on FDT for this info.

Remove unused tegra_dma_tag

GC unused tegra_dma_bootstrap function.

Chip detection and MP spinup code for Tegra210

Get rid of tegra_cpuinit after scanning fdt and attach the cpufreq support
to the /cpus node. Use regulator API instead of poking directly at the I2C
controller to set voltages.
