[ARM] 4017/1: [Jornada7xx] - Updating Jornada720.c
* HP Jornada 720 uses epson 1356 chip for graphics. This chip is compatible with s1d13xxxfb driver. * HP Jornada 720 uses a Microprocessor Control Unit to talk to various hardware. We add it as a platform device in jornada720_init() * We provide pm_suspend() to avoid unresolved symbols in apm.o. We are unable to truly suspend now, hence the stub. * Speaker/microphone enabling got removed because it will be placed in the alsa driver.
