Andrew Burgess b5ffee3181 gdb/riscv: Add target description support
This commit adds target description support for riscv.

I've used the split feature approach for specifying the architectural
features, and the CSR feature is auto-generated from the riscv-opc.h
header file.

If the target doesn't provide a suitable target description then GDB
will build one by looking at the bfd headers.

This commit does not implement target description creation for the
Linux or FreeBSD native targets, both of these will need to add
read_description methods into their respective target classes, which
probe the target features, and then call
riscv_create_target_description to build a suitable target
description.  Until this is done Linux and FreeBSD will get the same
default target description based on the bfd that bare-metal targets
get.

I've only added feature descriptions for 32 and 64 bit registers, 128
bit registers (for RISC-V) are not supported in the reset of GDB yet.

This commit removes the special reading of the MISA register in order
to establish the target features, this was only used for figuring out
the f-register size, and even that wasn't done consistently.  We now
rely on the target to tell us what size of registers it has (or look
in the BFD as a last resort).  The result of this is that we should
now support RV64 targets with 32-bit float, though I have not
extensively tested this combination yet.
