[PATCH v3 16/19] target/riscv/cpu.c: make misa_ext_cfgs[] 'const'

[Daniel Henrique Barboza]

The array isn't marked as 'const' because we're initializing their
elements in riscv_cpu_add_misa_properties(), 'name' and 'description'
fields.
In a closer look we can see that we're not using these 2 fields after
creating the MISA properties. And we can create the properties by using
riscv_get_misa_ext_name() and riscv_get_misa_ext_description()
directly.

Remove the 'name' and 'description' fields from RISCVCPUMisaExtConfig
and make misa_ext_cfgs[] a const array.
