lib: sbi: Add support for Svade and Svadu extensions

Browse Source 
Add support for Svade and Svadu extensions. When both are present in the
device tree, the M-mode firmware should select the Svade extension
to comply with the RVA23 profile, which mandates Svade and lists Svadu as
an optional extension.
