The csf_spl.txt and csf_fit.txt templates contain file paths which must
be edited for the location of your NXP CST generated key files.
Streamline the process of signing an image by assigning unique var names
to these which can be expended from env variables in the csf.sh script.
The following vars are used:
SRK_TABLE - full path to SRK_1_2_3_4_table.bin
CSF_KEY - full path to the CSF Key CSF1_1_sha256_4096_65537_v3_usr_crt.pem
IMG_KEY - full path to the IMG Key IMG1_1_sha256_4096_65537_v3_usr_crt.pem
Additionally provide an example of running the csf.sh script.

The current mechanism is unnecessarily complex. Simplify the whole mechanism
such that the entire fitImage is signed, IVT is placed at the end, followed
by CSF, and this entire bundle is also authenticated. This makes the signing
scripting far simpler.

The current name is inconsistent with SPL which uses CONFIG_SPL_TEXT_BASE
and this makes it imposible to use CONFIG_VAL().
Rename it to resolve this problem.
