Tegra: remove ENABLE_SVE_FOR_NS = 0

The SVE CPU extension library reads the id_aa64pfr0_el1 register to
check if SVE is enabled. Tegra platforms disabled ENABLE_SVE_FOR_NS for
pre-8.2 platforms, but this flag can safely be enabled now that the
library can enable the feature at runtime.

This patch updates the makefile to remove "ENABLE_SVE_FOR_NS = 0"
as a result.
