drm/panthor: Use the BITS_PER_LONG macro

Browse Source 
sizeof(unsigned long) * 8 is the number of bits in an unsigned long
variable, replace it with BITS_PER_LONG macro to make them simpler.

And fix the warning:
	WARNING: Comparisons should place the constant on the right side of the test
	#23: FILE: drivers/gpu/drm/panthor/panthor_mmu.c:2696:
	+       if (BITS_PER_LONG < va_bits) {
