video: tegra: host: add per device module-reg-read-write ioctl
- currently, the ioctl NVHOST_IOCTL_CTRL_MODULE_REGRDWR is
a part of nvhost-ctrl node
- however, it doesn't deal with host1x. infact it read/write
actual module registers
- for this kernel needs to maintain a list of all nvhost_devices
registered for a SoC. currently, this is encapsulated within
nvhost_bus which provides a iterator to walk these device list
- however, once we phase out nvhost_bus and adopt the platform_bus
we do not have a way to know the list of these devices
- this commit adds a new per-device ioctl for module register
read-write functionality
- all the new code should be using this new per device ioctl. the
old will be removed as soon as all the clients are ready to use
new ioctl
