f2cf7feb80 ARM: tegra20: tegra30: support EBTUPDATE on non-encrypted devices 
Re-crypt support was extended to devices without burnt SBK. In case
SBK is not set, place from where it is read is filled with zeroes.
This patch adds support for ebtupdate function to detect nosbk device
and avoid crypto operations for it.
