Explicitly list dependence on Smcsrind/Sscsrind

[christian-herber-nxp]

Currently, this statement is in Smclic:

Access to CLIC registers clicintctl[i], clicintattr[i], clicintip[i], clicintie[i], and clicinttrig[i] utilizes the
Indirect CSR Access extension (Smcsrind/Sscsrind).

Normally, extensions explicitly list the extensions they depend on.
Suggest to add this to Smclic:

The Smclic extension depends on the Smcsrind extension.

and to change this:

The ssclic extension depends on the smclic extension.

to

The Ssclic extension depends on the Smclic and Sscsrind extensions.
