Samuel Holland ef4ed2dda7 lib: sbi_scratch: Apply bounds check to platform hart_count ...

The internal limit on the number of harts is SBI_HARTMASK_MAX_BITS, as
this value determines the size of various bitmaps and arrays (including
hartindex_to_hartid_table and hartindex_to_scratch_table). Clamp the
value provided by the platform, and drop the extra array element.

Update the documentation to indicate that hart_index2id must be sized
based on hart_count, and that hart indexes must be contiguous. As of
commit 5e90e54a1a ("lib: utils:Check that hartid is valid"), there is
no restriction on the valid hart ID values.
