ARM: 8679/1: bitops: Align prototypes to generic API

include/asm-generic/bitops/find.h declares:

extern unsigned long
find_first_zero_bit(const unsigned long *addr, unsigned long size);

while arch/arm/include/asm/bitops.h declares:

#define find_first_zero_bit(p,sz)	_find_first_zero_bit_le(p,sz)
extern int _find_first_zero_bit_le(const void * p, unsigned size);

Align the arm prototypes to the generic API, to have gcc report
inadequate arguments, such as pointer to u32.
