riscv: create Kconfig architecture features for new parts

RISCV parts can be created with any one of four CPU modes enabled,
with or without PMP, and with either 32 or 64 bit XLEN.

In anticipation of parts to come, create the Kconfig variables for these
architecture attributes. We do not create more than we need for coreboot.

With this change, and a conditional compilation of PMP as an example,
hifive still builds.
