So that riscv_fill_hwcap() can use riscv_isa_ext to probe for single
letter extensions, add them to it. riscv_isa_ext_data grows a new
member, signifying whether an extension is multi-letter & thus requiring
special handling.
As a result, what gets spat out in /proc/cpuinfo will become borked, as
single letter extensions will be printed as part of the base extensions
and while printing from riscv_isa_arr. Take the opportunity to unify the
printing of the isa string, using the new member of riscv_isa_ext_data
in the process.

Instead of defining a new member, could we just infer this by making a
macro like #define MULTI_LETTER(name) (name[0] && name[1])?

Or don't even try to be clever like this and just call strnlen on the
name & check if it is 1? It's only used in 2 places.
