riscv: implement user_access_begin() and families
Currently, when a function like strncpy_from_user() is called,
the userspace access protection is disabled and enabled
for every word read.
By implementing user_access_begin() and families, the protection
is disabled at the beginning of the copy and enabled at the end.
The __inttype macro is borrowed from x86 implementation.
