[PATCH v4 0/2] riscv: support new isa extension detection devicetree properties

[Conor Dooley <conor@kernel.org>]

From: Conor Dooley <conor.dooley@microchip.com>

Making it a series to keep the standalone change to riscv_isa_string()
that Drew reported separate.

Changes in v4:
- Other than a rebase, add a helper for the mxl_max to xlen conversion

Changes in v3:
- g_free() isa_extensions too
- use misa_mxl_max rather than the compile target for the base isa
- add a new patch changing riscv_isa_string() to do the same
- drop a null check that cannot be null
- rebased on top of Alistair's next branch

Changes in v2:
- use g_strdup() for multiletter extension string copying
- wrap stuff in #ifndef to prevent breaking the user mode build
- rename riscv_isa_set_props() -> riscv_isa_write_fdt()
