[PULL,29/54] target/riscv/cpu.c: mark extensions arrays as 'const'

Commit Message

From: Daniel Henrique Barboza <[e-mail]>

We'll need to export these arrays to the accelerator classes in the next
patches. Mark them as 'const' now because they should not be modified at
runtime.

Note that 'riscv_cpu_options' will also be exported, but can't be marked
as 'const', because the properties are changed via
qdev_property_add_static().
