pk: Fix __clear_cache() compilation issue with recent compilers (#240)
Using recent compilers we get the following error message:
../pk/pk.c: In function 'run_loaded_program.constprop':
../pk/pk.c:177:3: error: both arguments to '__builtin___clear_cache'
must be pointers
177 | __clear_cache(0, 0);
| ^~~~~~~~~~~~~~~~~~~
Let's use the existing function __riscv_flush_icache(),
give it a header with a prototype and use it to
emits the FENCE.I instruction directly.
See #239
