csky: uaccess.h: Coding convention with asm generic
Using asm-generic/uaccess.h to prevent duplicated code:
- Add user_addr_max which mentioned in generic uaccess.h
- Remove custom definitions of KERNEL/USER_DS, get/set_fs,
uaccess_kerenl
- Using generic extable.h instead of custom definitions in
uaccess.h
Change v2:
- Fixup tinyconfig compile error, "__put_user_bad"
- Add __get_user_asm_64
