Richard Henderson fedb88bd32 fdt: Use bswapN instead of bswap_N
Fixes the libfdt enabled build for hosts that have <machine/bswap.h>.

The code at the beginning of qemu/bswap.h is attempting to standardize
on bswapN.  In the case of CONFIG_MACHINE_BSWAP_H, this is all we get.
In the case of CONFIG_BYTESWAP_H, we get bswap_N from the system header
and then wrap these with inline functions to get bswapN.
