From: Zhang RunMin <runmin.zhang at ingenic.com>
In `csr_read_allowed` and `csr_write_allowed` macros, has already
converted second param to `ulong`. So delete redundant `ulong`
where uses csr_read/write_allowed macros.

v2:
- Fix similar problems in:
lib/sbi/sbi_hart.c
lib/utils/irqchip/imsic.c
v1:
- Delete redundant ulong in:
lib/sbi/sbi_dbtr.c
