ARM, i386, m68k and ppc all have identical implementations of strmhz(). Other architectures don't provide this function at all.
ARM, avr32, blackfin, i386, m68k, mips and sparc all have identical implementations of init_baudrate(). Other architectures don't provide this function at all.
This patch moves strmhz() and init_baudrate() into lib_generic, reducing code duplication and providing a more unified API across architectures.
