lib: sbi: Add missing sscrind and sscfg extensions in sbi_hart_ext[]

Browse Source 
The sbi_hart_ext[] array is missing these two extensions ids. It is
expected that this array contains all the extensions declaration at the
same index of the SBI_HART_EXT_* define. Without this, when adding a new
extension, there is a mismatch between ids and extension names and it
can even display corrupted extension names.
