drivers/char/misc.c: use bitmap/bitops functions for dynamic minor number allocation
Use DECLARE_BITMAP(), find_first_zero_bit(), set_bit() and clear_bit() instead of rewriting code to do it with the minor number dynamic allocation bitmap. We need to invert the bit position to keep the code behaviour of using the last minor numbers first, since we don't have a find_last_zero_bit.
