ref-manual: add FIT_KERNEL_COMP_ALG*
Add FIT_KERNEL_COMP_ALG and FIT_KERNEL_COMP_ALG_EXTENSION. Examining OE-Core commit 5c72105e2973e613b5c0f0e6310ffdea6e56c6c7 and the associated code, these do not enable arbitrary selection of compression algorithm - only disabling compression - so document them accordingly.

:term:`FIT_HASH_ALG`
Specifies the hash algorithm used in creating the FIT Image. For e.g. sha256.
+ :term:`FIT_KERNEL_COMP_ALG`
+ Compression algorithm to use for the kernel image inside the FIT Image.
+ At present, the only supported values are "gzip" (default) or "none"
+ If you set this variable to anything other than "none" you may also need
+ to set :term:`FIT_KERNEL_COMP_ALG_EXTENSION`.
+
+ :term:`FIT_KERNEL_COMP_ALG_EXTENSION`
+ File extension corresponding to :term:`FIT_KERNEL_COMP_ALG`. The default
+ value is ".gz".

:term:`FIT_KEY_GENRSA_ARGS`
Arguments to openssl genrsa for generating RSA private key for signing
fitImage. The default value is "-F4". i.e. the public exponent 65537 to
