On RV64,"unsigned long" is 64bit and "unsigned int" is 32bit. So in
function "pmp_get" and "pmp_set", if "pmpcfg_shift >= 32", "0xff << pmpcfg_shift"
will go beyond "unsigned int" width. This patch tries to fix this issue.
In function 'pmp_get':
cfgmask = (0xff << pmpcfg_shift);
-->
cfgmask = (0xffUL << pmpcfg_shift);
In function 'pmp_set':
cfgmask = ~(0xff << pmpcfg_shift);
-->
cfgmask = ~(0xffUL << pmpcfg_shift);
