asm-generic: updates for 6.0

There are three independent sets of changes:

 - Sai Prakash Ranjan adds tracing support to the asm-generic
   version of the MMIO accessors, which is intended to help
   understand problems with device drivers and has been part
   of Qualcomm's vendor kernels for many years.

 - A patch from Sebastian Siewior to rework the handling of
   IRQ stacks in softirqs across architectures, which is
   needed for enabling PREEMPT_RT.

 - The last patch to remove the CONFIG_VIRT_TO_BUS option and
   some of the code behind that, after the last users of this
   old interface made it in through the netdev, scsi, media and
   staging trees.
