Fix the function prototypes to use the common parameter name 'addr'
instead of 'p' (common to arch-specific implementations of these
functions).
This avoids the kernel-doc warnings:
Warning: include/asm-generic/bitops/lock.h:19 function parameter 'p'
not described in 'arch_test_and_set_bit_lock'
Warning: include/asm-generic/bitops/lock.h:41 function parameter 'p'
not described in 'arch_clear_bit_unlock'
Warning: include/asm-generic/bitops/lock.h:59 function parameter 'p'
not described in 'arch___clear_bit_unlock'
Fixes: 84c6591103db ("locking/atomics, asm-generic/bitops/lock.h: Rewrite using atomic_fetch_*()")
Signed-off-by: Randy Dunlap <rdunlap@infradead.org>

v2: rebase & resend
v3: change the function parameter names instead of the kernel-doc
comments (Yury) (Fixes: can be kept or dropped at maintainer discretion.)
