Subject: [PATCH] Tegra: enable 'WARMBOOT_ENABLE_DCACHE_EARLY' flag

This patch enables the 'WARMBOOT_ENABLE_DCACHE_EARLY' flag to enable
D-cache early, during the CPU warmboot sequence. This flag is applicable
for platforms like Tegra, which do not require interconnect programming to
enable cache coherency.
