Create new configuration keywords:
RsaKeyModulusFile: pubkey modulus
RsaPssSigBlFile: bootloader rsa pss signature
RsaPssSigBctFile: bct rsa pss signature
Sample Configuration file update_bl_sig.cfg
RsaKeyModulusFile = pubkey.mod;
RsaPssSigBlFile = bl.sig;
where pubkey.mod and bl.sig are files that contain the public key
modulus and bootloader's rsa-pss signature respectively.
public key modulus and signature are created through utilities
outside cbootimage.
Command line example:
$ cbootimage -s tegra210 -u update_bl_sig.cfg image.bin
image.bin-bl-signed
Above three new keywords added in this CL are only implemented
support for T210.

This is the function name used by tegrasign. I am open if you have a better
name. The reason for the swap because the string actually is a 256 byte long
number. Tegra soc handles a number by little endian byte order.

Nit: You could make "in" const to since it's not written.
OK.
Actually this function allows output pointing to input, ie, reversing itself in byte order.
Presumably however, the "in" pointer is only used for reads and the
"out" point is only used for writes, so "in" can still be const?
