ESP: fix ESP DMA access when DMA is not enabled

Sending ESP a command caused it to trigger DMA immediately
even if DMA was not enabled at the DMA controller.

Add a signal from DMA controller to ESP to tell ESP about changes in
DMA enable bit. Also use the correct function for setting up GPIO outputs....

Rearrange block headers

Changing block.h or blockdev.h resulted in recompiling most objects.

Move DriveInfo typedef and BlockInterfaceType enum definitions
to qemu-common.h and rearrange blockdev.h use to decrease churn.

qemu_ram_alloc: Add DeviceState and name parameters

Remove useless device dependency of HAS_AUDIO

System architecture dictates whether HAS_AUDIO is defined. It's then
useless to check for HAS_AUDIO in files which are only used on those
architectures which always have audio.

hpet/rtc: Rework RTC IRQ replacement by HPET

Allow the intercept the RTC IRQ for the HPET legacy mode. Then push
routing to IRQ8 completely into the HPET. This allows to turn
hpet_in_legacy_mode() into a private function. Furthermore, this stops
the RTC from clearing IRQ8 even if the HPET is in control....
